At this point I think I just need to sign my paychecks right over to Think Geek.
I am not a fan of car window family decals. I just don't get the point of wanting weird stick figure representations of the members of your family (really only identifying their gender) on the back of your car.
I am however, seriously considering buying some of these Officially Licensed Star Wars Decals. for $14.99 you get 50 decals, with 19 separate characters to choose from. So Mom's truck can have Han+Leia= Yoda and R2-D2 and Dad's car can have Darth Vader + Padme = Kid Luke and Leia. The set comes with 12 Stormtrooper Kid decals, so even the largest geek families can represent!
