My Foray into Post-Modern Humor

The following joke is loosely based on my day at work, and borrows liberally from the oral tradition, specifically my sister-in-law's bran muffin joke.

An epidemiologist, two chihuahuas and a unicycle walk into a meeting. The first chihuahua says, "Man, it spells like dog puke in here". "My bad," says the second chihuahua. And the unicycle says "Aaaah! Talking chihuahuas!"
