Rat Bravery

Three rats are sitting at the bar talking bragging about their bravery and toughness.

The first says, "I'm so tough, once I ate a whole bagful of rat poison!"

The second says, "Well I'm so tough, once I was caught in a rat trap and I bit it apart!"

Then the third rat gets up and says, "Later guys, I'm off home to harass the cat."
