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."
Luckily these filthy animals were then beaten to a pulp by the barman who, fearing he had broken several licensing laws, including serving alcohol to rats that were clearly under 18 (A rat only lives 2-3 years) several hygiene infractions and then allowing the final rat to drive home, intoxicated, to twat the cat would have led to one presumes a summons.
It was these factors that resulted in him squashing the vermin, talking though they were, with a heavy mallet.
