We've all seen him in South Park, in Family Guy, in The Grimm adventures of Billy and Mandy.... Now I have just spotted him in yet another show. The Mr. Men Show. In the episode called "Mall" (just aired a few minutes ago), there was a bit where this dude was going down the up escilator, following this was some kind of dance segment thingy. Optimus Prime appears almost immediately afterward. You'll have to look close, he's in the wrong colors, blue/green if I recall, but he's there in the background as the camera is panning to the right. I'm going to try to find the episode and get screencaps to verify, so for the time being please take this with a grain of salt as I have been sick/medicated, and my eyes may have been tricking me. *edit* BLAMMO! Optimus Prime AND R2-D2 ftw! SPECIAL THANKS TO JOSHTHERIPPER AND TO IACONHUB!
