Congrats, David Letterman

Tuesday marked a major milestone for David Letterman: 30 years of late-night broadcasts. So how did he celebrate? With a little help from some old friends. Long-time staffers delivered the night's top 10 with quips like "My therapist says I have Stockholm Syndrome" and "You're incompetent." Bill Murray brightened Letterman's night with a cupcake covered in 30 candles. The two Midwesterners even went outside to throw around the football for a little pre-Super Bowl fun. Regis Philbin joined in as referee. RELATED: Video: 20 moments from David Letterman's 30 years in late night
