Two crocodiles lazing in a river, one says "I can't understand why you're so much bigger than me, we're the same age, we live in the same river & we both eat politicians"
The second one says "How do you eat your politicians?"
The first one says "Well I crawl up the riverbank, I lay under one of their Lexus cars & wait, as they are getting in their cars I leap out & grab them by the leg, I shake the shit out of them then drag them to the river & eat them"
"Ah" says the second croc "that's where you are going wrong, you see once you have shaken the shit out of them all you are left with is an arsehole & a briefcase."
