Stomach ache laughter

A man walks into the dentist's office and after the dentist examines
him, he says, "that tooth has to come out. I'm going to give you a shot of
Novocain and I'll be back in a few minutes." He grabs the doc's arm,
"No way. I hate needles I'm not having any shot!"

So the dentist says, "okay Jim,we'll have to go with the gas." He
replies,"absolutely not. It makes me very sick for a couple of days.
I'm not having gas." So the dentist steps out and comes back with a glass of water, "here," he says. "Take this pill." The man asks, "What is it?" The doc replies, "Viagra."

Jim looks surprised. "Will that kill the pain?" "No," replies the
dentist, "but it will give you something to hang on to while I pull
your tooth!"
