Edit: We've had some good ones so far!
alw2671: A bottle of VIP Gin, a huge cucumber, and a tube of Preparation H.
Beth: Pregnancy test, coat hangers, drano.
Obvious Guy: Sponge-bob DVD, Cattle Prod and chocolate.
SirRealOne74: Toothpaste, toothbrush, floss. Because that'd be a first for a WalMart customer.
10/10, lol'd hard.
