Okay, just don't get red-faced and embrassed by soem of the items found.
(Instead, think of who can be pranked into submission by whatever is found.)
Shopping is a tradition in my family, and it carried over to my time as a step-father.
I was blessed to have a step-daughter that was as much of a practical joker as I, and who didn't mind having to drag me from a store right before getting us banned from the place.
(It's bad when a gothic store called "Jezebella's" kicks you out.)
No problem! I've been kicked out of stores before, stores and theaters mostly. Never gotten kicked out of a porn shop but I did get escorted out of a joke shop. It's fun and no damage done.
