Screwing some one

There was a loser who couldn't get a date. He went to a bar and asked this one
guy how to get a date. The guy said, "It's simple. I just say, I'm a lawyer." So
the guy went up to a pretty woman and asked her out. After she said no, he told
her that it was probably a good thing because he had a case early in the
morning.
She said, "Oh!!!! Your a lawyer?"
He said, "Why yes I am!", so they went to his place and when they were in bed,
screwing, he started to laugh to himself.
When she asked what was so funny, he answered,"Well, I've only been a lawyer
for 15 minutes, and I'm already screwing someone!"
