This might be one of the weirder ones I've had in a while.
I'm on an ordinary school bus with a bunch of strangers, and I look up front to see that the driver is the Joker (the creepy Heath Ledger version, not the campy Jack Nicholson), and he has just kidnapped us. Nobody on the bus believes me, so I grab one woman's chin and force her to look at the driver. He keeps looking backwards at all of us and laughing, and as he does so his head keeps growing until it can't fit through the door of the bus.
He lets us off at our stop and stays on the bus (presumably because of his massive cranium) and I know I have to do battle with a small kid wearing huge glasses. But this battle involves me being the goalie as the kid kicks soccer balls at me. I totally block everything he kicks, and the kid starts bawling when I defeat him. The Joker's head then shrinks back down to normal size.
