It would be really cool if Gordy Leong would make a very memorable thread entrance.
I want a t-shirt with that image all big and fish-eyed on the front, and that pic of Mr. Fivehead somewhere, maybe as just a stamp in the bottom right corner or something. And then on the all-important back (visible to curious onlookers who might wonder if you're shirking your responsibilities as you're playing on location), could be in an official-looking font "Truancy Officer".
Quick 'n dirty:

Arcades in the 70s were often pretty shady places. I romanticize those times, but I also know there was a lot of fairly sleazy stuff going on that I was happily oblivious to, being a kid--and that which I identified I knew well enough to avoid, thankfully. Never had any bad experiences, and really at that age being there was all about the games, and everything else was a distant second.
