Even Joan Rivers knows that when it comes to Botox, you can have too much of as a good thing.
The plastic surgery-happy comedienne showed up on the "Today" show Tuesday to promote her new book "I Hate Everyone… Starting with Me" and dropped a bomb on Kathie Lee and Hoda:
Joan is quitting Botox!
For now, that is. Why?
"Because Betty White's bowels move more than my face," she cracked.
"You could say to me anything. I'd go, 'Uh-huh.' My birthday, I couldn't blow out the candles on the cake!" she said.
Joan's face might not be getting any more shots of the botulinum toxin for a while, but her barbs were as sharp as ever. Asked about aging, she said the worst of it was the men.
"A guy gave me a hickey, left his teeth in my neck," she said.
She also quibbled with Paris Hilton's gripe that Kim Kardashian had ripped off her schtick. "How can you steal a rash?" she shrugged.
