It was confession time on 'The Tonight Show' (Weeknights, 11:35PM ET on NBC) for Jack Black. The voice of 'Kung Fu Panda' had a promotional opportunity to hold a baby panda bear.

"I've heard stories that if you hold a baby panda in your arms that you achieve inner peace," he said. "So I was pretty psyched about it."

Unfortunately, the veterinarian that was there to help with this seemed intent on freaking him out as much as she possibly could. First she told him simply that they don't like to be touched. Then she showed him a scar on her face.

"Do you see this scar here? They have claws, very sharp claws. They're bears!" she said, according to Black.

Leno had the footage that was supposed to be this great promotional moment for the new film, but instead it showed Black sheepishly avoiding anything and everything to do with the bear.

"He didn't really look like a killer now that I look at it back," Black said after seeing the footage. "I think she just didn't want me to have inner peace."
