sauce for the gander

So there's one of these hilarious pop culture mashup t-shirt vendors at fan conventions who's now selling shirts that say "(name of convention) Is My Super Bowl". And some of the people who run the conventions that are named on these shirts are like, "how dare they use the name of our convention, that's copyright infringement or whatever." And I'm like, have you LOOKED in your dealers room lately?? It's copyright infringement T-shirt heaven in there!
