Two guys walk into a photo booth and make out. Photo booth doesn't say anything but snap because photo booths don't discriminate, even in 1953. Bet they ran outside of it to collect their little strip of photos very quickly though, lest whoever else was in line grab them and curl their fingers into a fist. And you haven't lived until you've been punched by a gay hating four year old in 1953. See, Mr. Rogers hadn't come along yet to calm everyone the fuck down about everything.
Check out the pucker of the guy on the right. And no, that's not Harrison Ford. It's his dad. It's a wonder Harrison got born.
