Here are 10 of the most popular responses, ranging from obvious talking points down to some sillier and more obscure choices:
#1 TV news, queues, health care and more
Americans in general are a patriotic bunch, quick to toot our own horns when it comes to military might, blockbuster movies, dominance in real sports, and, at least in one former expat's case, having readily available peanut butter and big refrigerators.
The British, however, are altogether different. They certainly have a deep love for their homeland, but their proclivity for whinging about life in the United Kingdom is as reliable as the London gloom.
However, if pressed into action, Brits are keen to wave the Union Jack in the face of any uppity American claiming superiority. And they tend to be really good at it.
So on Tuesday when somebody with the cyber-handle "ponypatrol" asked: "What does Britain do better than America?" it's no surprise the virtual flood gates opened.
Just one day after the question was posed, almost 32,000 comments had piled up on Reddit, making it perhaps the Internet's liveliest discussion of the day.
Here are 10 of the most popular responses, ranging from obvious talking points (like the first one) down to some sillier and more obscure choices:
#2 Health care
"There really is a notable divide between Americans who have lived in the UK and generally espouse the virtues of a socialised healthcare system, and Americans who've never left the U.S. but are convinced we're all living in some communist hell-pit" TheOtherNick
"American expatriate here. The NHS is s**t hot. Loved it so much I worked for them for years. I will say there are equally a lot of Brits who are clueless as just how amazing the NHS is" draccus
#3 Understatement
"WWII - England is being bombed daily (nightly) and Churchill refers to it as ‘The Unpleasantness'" accidental-poet
"'We had had a rather serious evening, you know.' Sir Cosmo Duff Gordon, describing his experience surviving the sinking of the Titanic" WhindSoull
#4 Roundabouts
"Mythbusters proved that they were way more efficient than 4-way stop signs" Dr00000100
"Oldsters avoid them like the plague. Exotics use them as skid pads at night in summer. Windows open in July and Michigan becomes an Italian race track, with shrieking V-12s and V-10s off in the distance" FalloutBos
"Roundabouts are only ‘complicated' if you never used them, after you get used to them you'll start hating every other kind of intersection" jmcs
#5 Queueing
"(The ‘ueue') are silently waiting their turn and are therefore perfect additions to any queue" FunkmasterFlash
"I've found that brits have more respect for the concept of a line. Every man their place, just wait your turn. Americans do it well, but there's an ego component that leads to a lot of people thinking they're just too good for lines" DionyKH
#6 Tea
"Us Brits fight with other Brits about the right way to brew and consume our tea. It's like a national pastime" ScarlettCaraway
"It's a British thing the good tea is for personal use and special guests only. Normal guests get PG Tips or go thirsty" Dd_8630
#7 Television news
"The BBC is greater than those cable news outlets in America" zp5
"I have a special love for the BBC world service. They can't make money off it, but listening to english news in francophone west Africa during rainy season when I was so homesick was just wonderful. I used to get choked up when they said ‘wherever you are, you're with the BBC'" jenesaisquoi
"As a Brit, seeing random news clips from America. It looks more like WWE than news. Always expecting Bill O'riley to jump up and start Stone Cold Stunning people" SettVisions
#8 Singing really offensive songs about opposing teams
"Nothing can beat the Scottish fans who welcomed the news of opposition player Andy Goram being diagnosed with schizophrenia by singing ‘there's only two Andy Gorams, two Andy Gorams'" ErvinPepper
"‘Adam Johnson's having a party, bring your homework and some Smartie's' is a favourite" NoDanaOnlyZuul
"They get worse, Adebayor, who left Arsenal and later joined Spurs, survived an attack from two gunmen on the Togo national team bus. Arsenal fans went on to sing: ‘Adebayor, Adebaaaayoooooor, three died in Togo, it should have been four'" brockers24
#9 Making fun of France
"A French diplomat once said to Lord Palmerston, ‘If I were not a Frenchman, I should wish to be an Englishman'; to which Palmerston replied: ‘If I were not an Englishman, I should wish to be an Englishman'" blaimjos
"‘The only thing the French should be allowed to host is an invasion.'" Quoted this as soon as France was announced as Euro 2016 hosts" GingerPrick
"In the words of Hugh Dennis, ‘The French have four faults: Their language, their food, their underarm hair and the fact that they are French'" nerdofblazingfire
#10 Accurate price tags
"In Britain, when you go into a shop, and the price is written on the item... that's how much it costs" Fahsan3KBattery
"It seems like anything else would be ridiculously illogical" Dr_Propofol
"This is the worst in restaurants. Most people from outside the U.S. do not understand that you're not only paying tax on your meal, but also ~20% tip that is not automatically added" TomWarden
#11 Ending TV series at the right time
"The season 9 finale [of The Office] was amazing, but that doesn't change the fact that season 8 and 9 never should have happened. Season 7 (when Michael Scott left) would have been the perfect finale, but the network wouldn't let it die" rg44_at_the_office
"Case in point, the two versions of House of Cards" alongdaysjourney
"Not just when to end, but also how to tastefully bring back shows and do little specials and things. I think British audiences tolerate cancellations better because popular shows often pop back up for one offs or even occasional full series. See Red Dwarf, Absolutely Fabulous, The Office, the IT Crowd, The Royle Family" BoomierBoom
