Alright, I have a few.

'Two blonds walk into a bar- you think one of them would have ducked'

'An egg and a chicken are in bed together, the egg lights a cigarette and says 'well I guess that answers that question'

'I went to the doctor last week, and I said Doc everytime I look in the mirror I throw up, whats wrong with me? The doc says, 'I don't know but your eye sight is perfect.'
