The dentist begins setting up the nitrous oxide when the man quickly objects.

“No way! I can’t handle the gas.

Just the thought of wearing a mask makes me feel like I’m suffocating!”

The dentist nods and asks,

“Would you be okay taking a pill instead?”

“Sure, I’m fine with pills,” the patient replies.

A moment later,

the dentist returns and hands him a pill. “Here’s a Viagra.”

Surprised, the patient exclaims,

“Viagra? I didn’t know that was a painkiller!”

“It’s not,” the dentist grins.

“But it’ll give you something to hold on to when I pull your tooth.”
