So what would a good anti-American joke be?

Well, I remember a scattering from my 1950s childhood. Back then anti-Americanism was pretty good-humored. Aside from some residual “over here, over-paid, over-sexed” resentments among adult males, we liked Yanks. Life with the Lyons was a great radio favorite. Humor featuring Americans poked fun at either (a) speech differences, or (b) supposed American ignorance of British customs & history. Samples:

Joke 1: Am American and an Englishman, strangers to each other, get into conversation on a train. Yank: “What kind of work d’you do?” Brit: “I’m a clerk.” Yank: “You’re a clerk? Then why ain’t you going ‘tick-tock, tick-tock’?”

Joke 2: A party of American tourists is being shown around Runnymede. Tour guide: “This is where King John signed Magna Carta, the great document of English liberties.” Yank: “When was that?” Tour guide: “1215.” Yank, turning to wife: “Aw, gee, honey, we just missed it by half an hour.”

That’s about as strong as it got.
