Frank Bank, who played bully Clarence "Lumpy" Rutherford on the classic TV series Leave It to Beaver died on April 13, according to People.
Frank sadly died one day after his 71st birthday, and no cause of death has yet been reported.
Jerry Mathers, who played the title character on the show, posted on Facebook: "I was so sad to hear today of the passing of my dear friend and business associate Frank Bank, who played Lumpy on Leave it to Beaver."
"He was a character and always kept us laughing," Jerry writes. "My deepest condolences to Frank's family."
Frank played Lumpy on the series from 1957-1963, and he reprised the role in the spinoff series The New Leave It to Beaver in the '80s.
Frank has also appeared from time to time on Hollywood Squares and Family Feud. He became a stock-and-bond trader in 1972, where he quickly started earning $300,000 a year.
Meanwhile, Frank was known as quite the lothario and had bedded a staggering number of females.
"A thousand women," Frank has been quoted as saying about his conquests. Kind of gives new meaning to the title of the sitcom he was on, no?
But Frank eventually settled down, and he is survived by his second wife, Rebecca, and two daughters from his previous marriage.
Our thoughts are with his family and loved ones during this difficult time.
