haaha,
I like it, anyone that would take serious offense to the sticker is a buster... I have plenty of jeep buddies and they all would get a kick out of that sticker, probly even put it on their own jeep for sh#&$ and giggles.
I say rock it, i would. I think that the pee on ford or jeep, chevy ones are much more of a direct slam, kinda like im peeing on you instead of just a little letter change thats funny.
cheers
