Tim Conway was the master of deadpan comedy. He could always keep a straight face during any skit...while making the rest of the cast descend into giggles. Here's a classic example in this Carol Burnett Show sketch called "The Dentist." Conway played a dentist trying to get through his first day on the job. Harvey Korman stared as his patient, and he had a really hard time stopping himself from laughing! Rest in peace Tim, we'll miss the laughs!
