I guess most of you weren't Conan O'Brien watchers. Until Conan moved the show to Hollywood in 2009, back in NY abe Vigoda was a semi-regular skit player on the show. Kind of like Larry Bud Melman on Letterman. Last Night Conan and Andy his announcer, talked about Abe and then ran a video of many of his skits. He mentioned sometimes they would think up an idea and call Abe three hours before showtime and he would be there. Here'a a time when he was Abe Vi'yoda'.
Here's a link to Conan's comments and the highlight video.
