The scene is a tacky country club. The manager is talking to a key employee. He tells the employee that the owner, Ronald Grope, is coming to visit, and that the employee ("John") will be the floor manager for a day. John is very happy until he's told what he can expect when meeting Ronald Grope.
"First, he's going to grab your crotch."
"WHAT!"
So the manager tells John that it's okay, there are plenty of female employees that have experienced this sort of behavior before. One will be stationed as a bartender and another, across the room, as a waitress. Whichever one is standing behind Ronald Grope will mime for him what he should do (I imagine Tina Fey and Amy Poehler, but I think that any female SNL cast member could do this improv).
I don't exactly know how the scene goes (it starts with Ronald Grope grabbing John’s crotch and then kissing him on the mouth), but it ends with the Ronald Grope's line:
"Come up to my apartment. I'll show you a screwdriver that Chicago's very top police gave me."
