Dick Wilson, the character actor best known as Mr. Whipple, has passed on.

Dick Wilson, the character actor and pitchman who for 21 years played an uptight grocer begging customers "Please, don't squeeze the Charmin," died today. He was 91.

The man famous as TV's "Mr. Whipple" died of natural causes at the Motion Picture & Television Fund Hospital in Woodland Hills, said his daughter Melanie Wilson, who is known for her role as a flight attendant on the ABC sitcom Perfect Strangers.

Wilson made more than 500 commercials as Mr. George Whipple, a man consumed with keeping bubbly housewives from fondling toilet paper. The punch line of most spots was that Whipple himself was a closeted Charmin-squeezer.

The first commercial aired in 1964 and by the time the campaign ended in 1985 the tag line and Wilson, a former Canadian airman and vaudeville veteran, were pop culture touchstones.

He also played a drunk on several episodes of Bewitched, as appeared as various characters on Hogan's Heroes, The Bob Newhart Show, and Walt Disney productions.
