January 27, 1976 –
Laverne and Shirley, a spinoff from Happy Days, starring Penny Marshall as Laverne De Fazio and Cindy Williams as Shirley Feeney, premiered on ABC-TV on this date.
Various cast members from Happy Days have talked about the vicious fights next door on set of Laverne and Shirley, so loud that they would listen with glasses to the wall. Garry Marshall has said in interviews that Cindy Williams and his sister, Penny Marshall, were immature during the production of Laverne and Shirley and did not handle stardom well, treating their coworkers in an abusive manner, and acting like prima donnas, endlessly fighting about who got more lines, etc.
