One more rather dumb thing that I used to joke about when I was a child/teen is this:

I would go around stating that I'm with the FBI. When people would say no you're not or let me see your badge or whatever I would say I'm with the Female Body Inspector Service of Investigations.

I would then go around to any semi attractive adult woman and say things like "miss, I'm with the Female Body Inspector Service of Investigation I will need you to take off your clothes so I can make sure you aren't smuggling drugs or poop" or I would go around wearing sunglasses pretending I had x- ray vision and I would tell said women about how I could see see their panties with my super x-ray vision.

I did this most commonly in psych wards to female staff solely to spite them or creep them out since I was always bitter about being sent there and I used to get in a lot of trouble for it haha
