A man is sitting on a bench in the park reading a Sunday Times.
Suddenly he throws the newspaper onto the ground and shouts out aloud sneeringly, "All politicians are ass-holes."
A man sitting next to him in a finely pressed suit says, "I take offence to that!"
The pissed-off guy asks him, "Why? Are you a politician?"
"No," he replies, " I'm an ass-hole."
