Two roaches

One day there were two roaches sitting in the corner of a bathroom while a human was taking a shower.
Roach1: Humans are so disgusting

Roach2: I know, they think they're getting clean, but look at this floor

Roach1: They are in the water that contains god knows what. Then when they step out their feet are in this dirt.

Roach2: Yea, then they dry off with that disgusting towel. How long has it been hanging there?

Roach1: And they put stuff on their bodies when they're done, sprays and lotions.

Roach2: Well, we know how to stay clean, we just lick ourselves.

Think about it the next time you take a shower. How clean are you?
