John Ratzenberger, Kate Levering

Say hello to daddy!

Cheers alum John Ratzenberger will guest-star in the upcoming season of Drop Dead Diva, TVGuide.com has learned exclusively.

The 64-year-old actor will play the estranged father of Kim Kaswell (Kate Levering), who, after decades of loyal service as a janitor at a Fortune 500 insurance company, suddenly loses his job and discovers his pension has been underfunded. Not one to take defeat lying down, he strikes back at his corrupt former employer by moving into the insurance company CEO's empty Bel Air estate until he's caught by the CEO, who tries to evict him. Larry will turn to Kim for legal help.
