This thought popped into your head before you remembered your name, so it's commanding "???" instead of your true name, Bitsy. But that's ok, we'll just plug Bitsy into the command, so that you don't get confused. This happens all the time actually, you forget your own name, then get a flood of ideas for things to do. That's fine though, we'll work through all the stupid ideas you had for antics while you were trying to remember your name.
But to address the idea from the peanut gallery... no, you will not be picking up the HORN, because you were not born yesterday.
Horns are standard issue in the circus penal system to boost morale of the prisoners. This is important to prevent CIRCUS RIOTS. Every cell is fitted with a horn to cheer up the prisoner. Studies show that when a horn is in the same room with someone, it is statistically impossible for that person's mood not to be improved.
However, due to budget cuts at the circus, usually there is no horn. It's often just painted on the floor or something, which makes a fool out of anyone who tries to honk it, thus crashing morale, and inching us ever closer to a dreaded and virtually always 100% lethal CIRCUS RIOT. You're quite sure some chicanery such as that is afoot with this horn.
