Bristol Palin and Jay Leno (Video)

Bristol Palin was Jay Leno's guest on Thursday's Tonight Show. She was promoting her book, Not Afraid of Life: My Journey So Far.

Don Rickles was also on the show. He was the first guest and remained during Bristol Palin's segment.

While Leno interviewed Bristol, Rickles was interjecting his comedy/commentary here and there.

The camera frequently caught Rickles mugging and rolling his eyes.

Sometimes, he was mocking Leno. At other times, he was reacting to Bristol.

Here's video:

Part 1: Bristol Palin talks about her new chin and her mom, Sarah Palin, running for President.

Part 2:Bristol Palin talks about new reality show and living with two guys.

It's funny how Palin haters responded to the interview on Twitter. They expressed their pleasure at Bristol being ridiculed by Rickles, as well as voicing their own insults.

Watching the segment, I found Rickles to be relatively restrained. He made fun of Leno's stupid questions. It's not as if he were on a mission to attack her.

In general, Leno treated Bristol with respect, and Rickles was being Rickles.

There was no real cruelty.

Nothing like the sort of stuff that David Letterman does.
