For me, the best T-shirts are ones that don't require knowledge of the brand at hand, but are enhanced when you do. Like, if I wear a shirt that says "I'm awesome, you are not," it's enjoyably obnoxious in a way everybody understands - but wrestling fans can identify you as a supporter of the Miz (on the other hand, my shirt with a picture of a skull-faced Triple H isn't because I'm a fan - I just liked the picture).
So this shirt above - if you're my age, or share any of my interests, you get that it's a Ghostbusters joke. But even if you don't, it's always good to answer "Yes." Because when you can bust a reference like that, and in 8-bit style, you are rolling like a geek god anyway.
