A man walks into a bar, sits down and orders a triple martini. The bartender says "What a coincidence, the only other person at the bar is that beautiful woman at the other end. She is also drinking triple martinis".

After a few sips of his drink, the man walks up to the woman and says, "Isn't it a coincidence that we are both having the same drink".
She replies "Yes! I am here because I am celebrating. After 20 years of trying I am finally pregnant!"

"What a coincidence" the man replied. "I am also celebrating.
After years of experimenting, I have invented a multicolored chicken. At this, the woman asked "How did you ever accomplish that!?".

"I had to try a lot of different cocks" he said. The woman replied
"What a coincidence!!!!"
