Ed Sullivan

The act that appeared most frequently through the show's run was the Canadian comedy duo of Wayne & Shuster making 67 appearances between 1958 and 1969. During a taping of Mason's monologue Sullivan off camera gestured that Mason should wrap things up by giving him two fingers meaning "two minutes left" as the show was suddenly shown live following an abbreviated address by President Lyndon Johnson which was expected to preempt the entire show. Johnny Carson also did a fair impression and even Joan Rivers imitated Sullivan's unique posture.
