From Springfield to New York, "The Simpsons" wanted to honor the "Late Show with David Letterman" after Letterman announced his upcoming retirement in 2015. Letterman leaves a career exceeding 30 years.
Watch above as Homer, Marge, Bart, Lisa, and Maggie take a city taxi to the landmark studio and take a page out of Itchy & Scratchy's book for those people who get in their way.
As Mashable says, "The longest-running scripted show paid tribute to the longest-running late-night talk show host this week."
Even Paul Schaffer gets a shout-out. "We'll miss you, Dave," ends the "Letterman Couch Gag."
