why not rig up a fog machine and get a big cast iron pot and have the wife dress up as a witch and stir it and add some green lights? and then you can dress up as a flying monkey and jump outa the back seat and scare the shit outa them. a wizard of oz kinda theme. or is that still a little to much for a church parking lot? maybe dress up as Jesus and put a cross on the top of the truck so you can haul it on the X instead of carrying on your back?
