Appearing on Bill Maher’s HBO show Friday night, actor/comedian Billy Crystal delighted in recounting a phone call he supposedly received from the late Robin Williams on the day of Ronald Reagan’s funeral in 2004.

Crystal, now a star of FX’s The Comedians, impersonated Williams impersonating Reagan calling from Heaven and wondering why it was so hot.

Watch the video clip to learn what amuses liberals, and note Crystal’s self-satisfied smile at the end.

Crystal, the Hollywood Reporter relayed last year, “shared the anecdote to rousing laughter Sept. 27 at San Francisco’s Curran Theatre, where Williams’ family and friends gathered for a private memorial.”
