I drew this in about five minutes, using a very thick Sharpie. It will only make sense to you if you're currently following the
Dick Tracy comic strip.

(For those not discerning enough to be Dick Tracy followers, the Pig on Wheels is a recurring character, of whom the fans keep clamoring for more. Despite this, he receives precious little on-screen time, and remains shrouded in mystery. Kind of like Boba Fett before Lucas let those buffoons feed him to the Sarlacc.)
