Jennifer Garner, Jessica Biel do 'Laverne and Shirley?' No more schlemiel, schlemazel, please

Director Garry Marshall took time on the "Valentine's Day" red carpet to joke about doing a "Laverne and Shirley" movie starring Jennifer Garner and Jessica Biel.

"We're gonna work on that," Marshall tells Extra. "My sister Penny and Cindy are gonna have a guest cameo. They're gonna walk "schlemiel, schlemazel" -- or they're gonna get tired in the middle and sit down."

Garner says she's dying to do it and Biel tried to sing the theme song.  "Dah, dah. Dah, dah. Something incorporated."
