from wikipedia:
In 1996, the show Late Night with Conan O'Brien wished to use him in a sketch, but were unable to locate him. The show mounted a highly publicized tongue-in-cheek search for Mayo called "Where's Grady?". After three weeks and over 50,000 calls to NBC from fans who claimed to have spotted him, Mayo finally appeared on Late Night with Conan O'Brien to a standing ovation from the audience, and the highest ratings Late Night with Conan O'Brien had seen in years. Mayo revealed that it was his mother who told him of the search after a repairman saw his picture in her house and told her she could be eligible for a reward.[1] At the time, Mayo was in Cape Canaveral, Florida as a member of the cast of the short-lived syndicated action/drama television show, The Cape. In the show, Mayo played Sweets, the lovable owner of the Moonshot Bar and Grill.
