"Dear Mr. Catchfire,
We demand your immediate apology for spontaneously combusting within a government building. Please remove your detached twitching leg and eyeball from our property at your soonest convenience. Don't forget to use our recycling depot on your way home for your parts, failure to do so will result in a fine.
Yours truly,
Them"

P.S.
Have a nice day!

That's how we do it round here. No one gets hurt after that.
