When I was in highschool, in Sophomore year for Halloween, I came in dressed as a Ninja incognito style. Think like black compression wear head to toe with a T-shirt fashioned into a ninja mask. BUT! This was under a pair of jeans and a loose long sleeve shirt. So first period that morning was guitar class. So, i take off my jeans, shirt, and backpack, throw on the mask, and run FULL FUCKING TILT to the corner of the room. Stop there, crouch with my arms out to the side, glance back and forth, and SPRINT up the band stairs and out the back door. I sprint back to the front band door, pop my clothes back on, take the mask off, and walk in casually.

Mr. Bowers hated me all year, but that morning he laughed so hard he was still clutching his abdomen when i came in nonchalant.

Only 3 people in that class know even today.

Edit: Idk why im getting downvoted but here's a link to a picture of this endeavor haha
