On which 1960s TV series did Rickles make a guest appearance as Sid? Sample dialogue:
"Sid, it's good to see you again. You haven't changed a bit, how long has it been now?"
"15 years! You forgot? Seoul, Korea, 1952. Don't you remember? We said if we both lived through this we'd get together again, huh, pal? Well, we almost didn't make it."
"Yeah, that was a tough bar, Sid."
