Dumbest thing you did in school/work

[Grey Acumen]

I swear to god, this is all true:

High School, I believe my senior year. my first period class was directly under the second period class. The first period class was also on the first floor and had a window that opened to the grounds outside.

At the end of one class, one of the students in my class acted as my wingman to get the teacher to step outside of the class, while another carried my bookbag up to the next period class. At this point I dove out of the window of my first period class and climbed the outside of my school building to get up to the window of my second period class, which was opened by the student who brought my bookbag up.

I climbed my school. To this day I still have people who occasionally recognize me as "Spiderman"
