Where It All Goes Down
Central Park in New York, Sunday Afternoon, 1959-ish
This is a one-scene play, so it's all set in one place: a quiet part of Central Park on a Sunday afternoon. The day is nice, the sun is warm, the birds are trilling, all is well with the world, except for the weird guy who babbles about lusty landladies and poisoning dogs and then attacks a dude and kills himself. Bet you weren't expecting that, huh?
The setting, in other words, is meant to be all nice and quiet and comfortable to contrast with the dirty, messy unpleasantness and absurdity of existence. Everything looks neat and ordered, with each animal in its cage, but it isn't. Be careful of the park—it's out to get you.
