Growing up, I had a 64 valiant that when the tranny started slipping (Thanks to my brother for revving and pooping the push button in first for peel outs) I wanted a vanity plate that said "FLATTERY" because flattery will get you nowhere!
on my wifes harley i got a plate that reads XPENSV.......but the best one i ever seen was up in canada a blonde was driving a boxster and the plate read WAS HIS!!!! ouch
