Do you think the silver surfer guy ever left the house? It looks like he just wrapped himself in tinfoil in the privacy of his own home. His mums probably gonna be pissed when she sees what he did to her ironing board.
The Joker and Harley Quinn ones look good because they do it as a profession. I stumbled across their website before. They also have people pose as The Penguin, The Mad Hatter, The Riddler, Batman, Black Canary, Catwoman, and..uh...more I think.
