It's Not A Telegram!
It's a Billy-Gram! In this sketch (written by future cast member Terrance Sweeney), guest host Elliot Gould and Ann Risley were living together without marriage when they receive a singing telegram for the girlfriend's birthday, sent by her parents---only it wasn't a regular singing telegram, it's a Billy-Gram! The deliverer, played in hammy style by Charles Rocket, sings the telegram denouncing the girlfriend's lifestyle. Check out Charles' hammy facial style.
