David Letterman celebrated 30 years in late-night television on Wednesday according to the Star Tribune.
Letterman commemorated the anniversary by having one of his favorite guests, Howard Stern, attend the "Late Night" show says the Star Tribune.
Letterman and Stern joked about how they had aged and pictures were shown from Stern's first visit to the show in 1984 says the Pioneer Press.
Long-time employees were also brought to the stage during the three-decade celebration. These employees presented the "Top Ten Things Staffers Would Like to Say to Dave on his 30th Anniversary in Late Night," according to the Pioneer Press.
