The other night on Stephen Colbert's show, he and guest Judd Apatow got to talking about old comedians who are not well-remembered. One of the names mentioned was that of Professor Irwin Corey, who I usually — maybe 75% of the time — found to be uproariously funny, especially because no one — including the host of any show he was on and Corey himself — seemed to know what he would do or say next.

It was the Professor's one and only appearance with Dave and it's hard to tell if right after it, Dave told his producers, "Never book that guy again!"
