Well, it sounds like a good idea...
I just know Aunt Veronica would end up smelling like a Dogon woman. With a tribe of Dogon nieces and nephews.
Brilliant Idea: Get two chemistry sets and when you are presented with the experimental atomizer for the trial spray by the eager young scientists / perfumers, pull the old switcheroo with an identical atomizer filled with Chanel No. 5!
Even more Brilliant Idea: After all the adults have done marvelling at how smart their children are to create such a wonderful fragrance - switch atomizers again so they get sprayed with El Stinko.
I love the holidays. It's all about togetherness and family. Only some of them might have to sit outside. Until the experiment wears off.
