Bush is like a slinky

This joke is not original to me (I can only wish I were that funny). I don't know who the original author was because I received it as part of a long chain of jokes passed by e-mail. I'd never heard it before, but for all I know it appeared on national TV (I don't watch TV). The original was phrased "Some people" but I tweaked it.

Bush is like a slinky: he doesn't do anything useful but you laugh like hell if you see him tumble down stairs.
