While back browsed the American Film Institute's lists -- not the most recent ones, but the ones around the turn of the century. Tried the "Court Jester", a Danny Kaye movie that turned out to be a real gem.
If you're into silliness and word play, pretty hard to beat. Just don't get scared at the musical number that opens the movie - I almost gave up, then and there, which would've been a big mistake.
Poisoned cup sets off a riff of stuff like "Is it the chalice with the palace or the vessel with the pestle?" Later clutzy Kaye is hypnotized into thinking he's the worlds greatest swordsman, but the effect toggles off and on when anyone snaps their fingers...you can imagine the fun they have with that. And early on there's what has to be one of films' greatest one liners, set up by a scam where his companion pretends to be deaf mute. Won't spoil it.
Its old school, but if you don't mind its got some great laughs
