'I love how you wash and condition your hair'
In the malt shop, where Greg's comment on how much seeing Marcia "wash and condition her hair" turned him on...no wonder "Cathy Lawrence" and Warren Mullaney decided to hook up! They looked soooo grossed out!!!!
And the scene where Jan pretends to "date" the dummy is worth mentioning too - especially when two dudes congratulate her on her "performance" - like they were watching an improvised monologue!!!
