Vice President Joe Biden and wife Dr. Jill Biden celebrated her 59th birthday, which is Saturday, at the Stanley Cup Game 4 Friday night. Willow Grove raised Jill Biden, a huge Flyers fan, who hangs a Danny Briere jersey on her door at home for good luck, wore a black Briere #48 t-shirt. The couple, and at least a dozen Secret Service agents, were in Super Box 13 at center ice where Comcast CEO Brian Roberts and Vice President David L. Cohen spoke to the Bidens. NHL Commissioner Gary Bettman also greeted Biden during the second intermission. "CSI" actor Paul Guilfoyle was rooting for the Flyers last night from Section 244. He has been a Flyers fan since attending Lehigh University where he played hockey as a defenseman and played at the Spectrum several times.. The Boston native was conflicted when the Flyers played the Bruins but regularly cheers for the Flyers and hopes to return to the Wachovia Center for Game 6 Wednesday. Andre Iguodala of the 76ers also caught the game from Super Box 13. He stopped at Mitchell & Ness (1318 Chestnut) Friday afternoon to pick up the Bobby Clarke throwback jersey and black and orange Flyers cap he wore to the game.
