There was a joke about a troll, a hag and a leprechaun who all go into a bar with humourous consequences. Albus Dumbledore heard this joke during the summer of 1994 and deemed it "excellent". Before he could reiterate it to Fred Weasley's outburst about the Triwizard Tournament, however, he was interrupted by Minerva McGonagall, and got back to the tournament's details.
