Here's an idea. Dress up in a trench-coat and hat and try to look as creepy as possible. Then, find someone you dont know's funeral, preferably an open casket funeral, and go lean into his coffin and say slowly but loud enough for everyone to hear, "checkmate. i win!" and then run off. The people at the funeral will either think you are the deceased's arch-nemesis or a super-villain, either way they won't forget you and it will raise questions about whether or not the dead person was in fact a superhero that noone knew of.
Moral Of The Story: If you crash a wedding you get free cake, but if you crash a funeral you create a superhero.
