I'm going to design a David Hogg costume for Halloween. I think I can sell millions of them.
It'll be the scariest thing you've ever seen, for sure.
Better rethink that, because the lawsuits coming your way would wipe out the profits. Too many people might just shot first and ask questions later if they thought David Hogwash was at their front door. Believing he was there to take their guns of course. 8>)
