yeah, i've seen the trucks, and i've seen t-shirts with that logo on. t-shirts like that are almost necessarily unfunny, but maybe this particular t-shirt is funny because it refers to an actually existing company. who knows.
You better remove it in case someone else sends it somewhere. There are tons of guests reading the fourm and you might want to send it elsewhere for money (I know there are other mags who do this)
Yeah it is, I remember when I used to go to school everyone on the bus would be like, "Hey look it's the jerkmobile!" when one passed by. I remember once, one of my friends did the jerk hand motion at one of the drivers and he pointed back towards his sign and started laughing his ass off like, "Yeah I know!" :lol
