Could it be that she didn't want to get her hair messy? It's a simple video thoough. To start with, Sam strips out of her yellow silk bra and pants (but keeps the helmet on) and lays on a plastic sheet. This could get messy.

My assistant is told to pour custard on her in a special way. She's going to have custard pants and a custard bra. After that's done we decide to add a basque--a fruit pie filling basque. Oh nearly forgot the strawberry syrup nipples!

She thinks that it is finished but is asked to sit up and she has multi-colored custard poured all over her and all over the helmet.Told you she didn't want to get her hair messy
