With just two weeks left of David Letterman as host of The Late Show, we can expect some great cameos and guest appearances from here on out. As such, during his monologue last night, Letterman was “interrupted” by a raucous audience member who turned out to be Will Ferrell reviving his Saturday Night Live impersonation of famed Chicago Cubs sportscaster Harry Caray.
Ever the gracious host, Letterman invited “Caray” up onstage, where he naturally mistook Letterman for Ed Sullivan and asked when Topo Gigio was coming out. Sadly, he didn’t stick around long enough to find out.
