We've all been there. You see something in a Transformers episode, or movie, or on a toy, or in a comic, or even online, and it's brilliantly funny or poignant or dramatic or triple-self-referential. And it's so good you find yourself trying to explain it to someone with no knowledge of Transformers beyond "Wasn't there a red truck one...?", but you realize fifteen minutes into the explanation that in order to 'get' the reference in full, they need to know about so much of the Transformers mythos and history that you could spend the next six hours providing the backstory for what might have been a quarter-second visual gag. So what, in your opinion, would take the longest time to explain compared to the actual amount of time or effort put into the reference itself? I'd nominate the Skids, Metroplex and Counterpunch gags in the Cybertron Enquirer, most of the fandom shout-outs in Beast Wars, and Longarm Prime getting Cliffjumper to dispose of a blue Autobot racecar.
