"We'll miss you, Dave."
David Letterman announced last week that he'll be retiring from the Late Show in 2015. Over the weekend, The Simpsons aired this special couch gag that bid farewell to the Late Show host. Either The Simpsons staff moved really quickly on this and got Letterman to record his part, or this was already in the can and they decided to roll it out after his announcement. The typical Simpsons episode takes 6-8 months to complete, and Letterman only made the announcement last Thursday. Regardless, Dave, you will be missed… but not for like another year.
