Max and the Statue(Max et la statue)

Max starts out at a costume store to get a costume for a party. He sees a suit of armor and purchases it. He wears it to the party and gets kind of drunk and passes out. In the meantime, a museum has a suit of armor ready for a new display. It is to be dedicated and some such. It comes up missing, so Max, passed out and still in his armor is put on display.
