The Green Lantern Light You Up T-Shirt is kind of aggressive, don't you think? It makes a lot of promises - hey, stop eyeballing my girlfriend or 'that's MY parking spot'! Guess it could also mean that maybe you're the light of the world to bring hope and peace to the four corners. Either or, really! Your choice. The 100% cotton Green Lantern Light You Up T-Shirt is a black t-shirt with the previously mentioned phrase and a small Green Lantern symbol at the bottom. You know you want it.
