 As the two stars congratulated each other on age and improving their looks, David flashed a photo from 1984 (yes, 1984!) when David had a whole lot of hair and get this -- Howard sported a mustache!  David quipped, "It looks like a guy who was on to talk about a career of writing bad checks." Howard suggested burning the picture but also added how thankful he was for the invitation to appear. "Back then, the fact that you asked me to be on a national television show was mind-blowing to me," said the SIRIUS host. VIDEO: CAMERON DIAZ MOCKS SUPER BOWL PDA WITH ALEX RODRIGUEZ BY FEEDING DAVID LETTERMAN POPCORN To fully mark the occasion, David brought his long-time employees to present the "Top Ten Things Staffers Would Like to Say to Dave on his 30th Anniversary in Late Night." According to the Washington Post, their executive producer Rob Burnett simply said, "You're incompetent." Aside from David reaching this mega milestone, who's your favorite go-to late-night show host?
