The childhood nickname of actress Jenna Elfman [born Jennifer Mary Batula] who starred as Dharma Freedom Finkelstein Montgomery, the free-spirited daughter of hippies on the sitcom DHARMA & GREG/ABC/1997-2002.
While growing up in Los Angeles, the kids at Jenna’s school gave her the nickname “Bucky Beaver” because of her overbite. But after three and a half years of orthodontia, Jenna had a wonderful smile and later, a winning career as an actress.
Note: Bucky Beaver was also the name of the friendly big-toothed rodent mascot who starred in a series of successful Ipana Toothpaste commercials created for Bristol Meyers Company in the 1950s.
The character appeared in the movie Grease (1978) during a slumber party scene at Frenchie’s house when Jan, a member of the “Pink Ladies” gang stood in front of the TV set, and mimicked the toothy grin of Bucky Beaver. She sang along with the commercial as Bucky delivered the bouncy “Brusha, Brusha, Brusha” jingle. Jan’s friends quickly tossed pillows at her to shut her up.
