Andy and I are walking on south campus, and discover a squirrel. The squirrel turns to run off, but instead grinds the side of its head against the ground.
Me : Did you see that?
Andy : Oh, definitely. I think we should amputate its limbs and keep it as a pet.
Me : Wouldn't it be mean to remove just the hind legs? See, because it could drag itself up a tree, but then couldn't get down because it has to face down when descending.
Andy : No, I mean remove all four legs. And then take it for walks. And by walks I mean "drags". And if anyone asks I'll say it's my pet caterpillar.
