Do you know the Great Purple Flower joke? Basically it's the House that Jack Built as an elaborate shaggy dog story, all about this Great Purple Flower.

Part 1, this guy hears about it, and he keeps asking about it, and everyone he asks beats the crap out of him, until eventually he's walking around in a brown suit picking up aluminum cans by the roadside, still asking people (a good 3-5 minutes).

Part 2, the guy asks another guy who says, "My son, I too have searched, blah blah." He then describes this house across the street, that has a great purple door, with a great purple knocker, and through it is a great purple staircase, and..... until eventually there's the great purple flower, and when you see it you wil understand. (easily 5-10 minutes, depending on audience)

Part 3, the guy runs across the road and is killed by a taxi. The moral of the story: look both ways before crossing the street.

Not exactly metafiction directly, but it's implicit.

Pete and Repeat were walking down the street. Pete fell in a hole. Who's left?

Kids always seem to like that one.
