TOD:
American Graffiti
Travels With My Aunt
The First Nudie Musical
The Creature Wasn't Nice
a couple of L/S episodes come to mind, although I liked most of them until the group moved to California from Milwaukee.
When she and Laverne pretended to be top fashion models.
When Shirley was the waitress and Laverne was the cook at a diner.
Any episode where she danced with Carmine.
The episode with MR BK when the girls had their names written on a restroom wall and two college guys called them up thinking they were going to vo-dee-o-doh.
