Not enough popular options for a poll yet, but my personal favourite is Elbonio's "MPUK Annual Trip Outside - Too much sunlight will melt us "
I think this strikes a beautiful balance between geek pride and not being swarthed in in-jokes that may only apply to some of the people going, or will look cringeworthily lame in a few month's time. Also, I don't want to wear t-shirts about manstacks and manjuice. You guys may get looked at funny. I'll just look like a whore. (This is not an invite to troll me)
Please post support and/or suggestions below, and a poll will be constructed later if necessary.
