The following is a true story, and not even the names have been changed to protect the innocent...
Going to my dentist's office for a cleaning one day, I was sitting in the chair, and chatting with the hygienist. She tells me she'd told a joke offended the doctor. "Oh, do tell!" I said.
I guess the good Dr. Yong didn't like the answer to the question: how do you blind an Asian?
No, she didn't like it a bit.
But, I liked the answer....
Put a windshield in front of 'em.
When Dr. Yong came in, I was sure to ask, "Hi Doc... so, how do you blind an Asian person?"
"That's not funny, Bill!"
"Oh, heck yes it is," I said.
Luckily, she knows I'm pretty damned fond of her, (and knew I'd been married to a Chinese woman forever and a day). Otherwise, that joke would have been a supreme act of courage to tell your dentist
before she works on you!
