It’s their birthdays and they’ll make you cry with laughter if they want to. In this new LiveCast, Christopher and Eric celebrate their mutual birthdays by giving away a prize pack of signed books to the person who leaves the most inappropriate birthday greeting on the show’s Party Line. Call 323-PEZ-TDPS before showtime to be entered to win. The celebratory insanity begins Sunday, March 15th 8 PM ET/ 5 PM PT at www.TheDinnerPartyShow.com.
