New

[[Black hat guy is walking.]] Black hat guy: New headcannon: [[A figure sits behind a desk with a computer on it.]] Figure: Yeah? [[Black hat guy has raised his hat, revealing a cannon that shoots the seated figure. The desk explodes and the figure is engulfed in smoke.]] <<BOOM>> Figure: Augh!

The nice thing about headcannnons is that it's really easy to get other people to believe in them.
