Today marks the 50th anniversary of the classic sitcom Leave it to Beaver, and while many of the show's original stars have left us (Hugh Beaumont, Stanley Fafara, Sue Randall, Richard Deacon), much of the main cast is still going strong, and five of them - Jerry Mathers, Tony Dow, Barbara Billingsley, Ken Osmond, and Frank Bank - appeared on Good Morning, America this morning to celebrate the day.

They've all kept busy over the years. Mathers appeared on stage in Hairspray this year and has appeared in several TV shows and wrote a book. Dow has directed many TV shows and movies over the years and is also an artist. Billingsley is an incredibly active 92 and even recreated her famous Airplane jive talk on GMA. Osmond became a cop - and was shot three times in the line of duty - and is now retired, and Bank (Lumpy Rutherford) is a financial expert who handles Mathers and Dow.

"Aw, cut it out Eddie, will ya?"

Ken Osmond, who played Eddie Haskell on 'Leave It To Beaver' but did not become a porn star after the show ended (that's an urban myth - he actually became a cop) is suing the Screen Actors Guild. He says that SAG has collected more than $8 million from foreign residuals but has not shared that money with SAG members and non-members. Osmond's attorney has also filed suits against the Directors Guild and the Writers Guild over the past few years. It could be a class-action suit if others join in. Osmond says that SAG will not show him their books.

"And Jerry Mathers as ... The Beaver."
