Beyond the Marquee readers who are fans of NBC’s new hit comedy “1600 Penn”, will be in for a treat when they tune in tonight, because our own BTM Host & Producer Jon Donahue will be making a special guest appearance on the show. Though we don’t want to give away any spoilers, we can give you a very vague hint…his scene takes place, in the White House! Donahue, who is certainly no stranger to acting on Television and in Motion Pictures assures us that tonight’s episode will be one of the funniest and memorable of the series yet. 1600 Penn is an American single camera television comedy series about a dysfunctional family living in the White House and stars Bill Pullman as the president of the United States with Jenna Elfman as the first lady. Look for it tonight, 9:30/8:30c only on on NBC. [UPDATED]: 1600 Penn’s show creator Mike Royce, following last night’s episode, tweeted to all his followers, including a nice shout out to Jon Donahue who he had worked previously together with on TNT’s Men of a Certain Age (click ahead to see Mike’s Twitter post)
