(CNN) – For the past 15 years, Tanya Johnson has been driving her boss nuts.
It’s not her job skills — Dr. Robert Szabo says Johnson is an excellent nurse — but rather her incessant knuckle-cracking that makes him want to strangle her.
“I kept telling her to stop, that it was bad for her,” Szabo said.
You’d think Johnson might have listened, given that Szabo is a hand surgeon at the UC Davis Medical Center and former president of the American Society for Surgery of the Hand.
But she just kept right on cracking.
“I told him, ‘Prove that it’s bad,’ ” she said.
