There's nothing worse than seeing a (poor) American comedian try to make an Australian crowd laugh.
“Haven't you guys heard of fly spray? I'm from New York, and over there we nuke the bastards!”
Oh.. you think that's funny?
“What's with all this rain?”
Yeah.. how 'bout that drought?
“Everyone knows the Italians are the most intimidating enthnic group.“
No. You're a ball bag. I don't care if you're black. Get over yourself.
And sooo loud too.
When they find out they are having a hard time winning the crowd, they start getting even louder and more aggressive.
