Farts are universally funny. Like sex jokes, they transcend time and language.

In fact, the oldest joke we have discovered was a fart joke:

Something which has never occurred since time immemorial... A young woman did not fart in her husband's lap.

Compare that to a different joke from about 200 years later:

A dog entered into a tavern and said, 'I cannot see anything. I shall open this one

It doesn't matter where or when you're from, nor does it matter what language you speak, farts are funny and will continue to be funny forever.
