In this vintage classic Jessie accuses Cherry of not trashing one of the temp office girls properly, and insists on showing Cherry how you properly trash a girl... by demonstrating on her.

In an earlier scene "Cherry Gunges Lacey" (https://reverend-slymsfords-splosher.umd.net/download_info/cherry-gunges-and-pies-lacey ), Jessie had asked Cherry to give Lacey The Treatment to improve her behaviour in the office.

Now Jessie calls Cherry in and tells her she clearly didn't do it well enough as Lacey's performance still hasn't improved. Jessie tells Cherry she can't have done it properly, and despite Cherry's protestations, she insists on showing her how it's done, with pies, gunge and custard. Of course they all end up going over poor Cherry.
