We have a new favourite joke, thanks to Plus reader, Ellen Hetland Fenwick!

A countably infinite number of men went into a pub. The first one ordered a pint. The second ordered a half-pint. The third ordered a quarter of a pint ... The barkeeper, with a face full of disgust, finally poured two pints and put them on the bar and said, "It's good when people know their limit."
