When I was a kid -- we're talking about forty-ish years ago -- I came across a joke that went like this:

an Englishman, an Irishman and a Scotsman get chatting at a bar. The Irishan and the Scot are big strapping lads of around 250lb, 6'6", muscles in their spit; while the Englshman is a typical weedy runt of 120lb, 5'4" (that's me, OK? Apart from the 120lb!). They get around to swapping jokes: the Irishman tells one that has the others splitting their sides, the Scot tells one that has them rolling on the floor.
Then it's the Englishman's turn:
"Well, there was an Englishman, an ... er, another Englishman, er, ... and ... er, well, another Englishman ..!"

I thought it was hilarious, but I've never raised a laugh with it since. There's nowt so queer as folk (can I say that?!)
