There are some seriously goofy food trucks out there. In fact, I saw an Italian one just today with a horn that played the Godfather theme. That being said, most of these trucks are pretty standard with a goofy name and a few silly puns. Jalopnik has ten of the craziest ones out there though, including one truck that specializes in the potentially deadly fugu fish.
Thanks, but I'll stick with the giant metal pig truck that serves pulled pork.
