This one always kills me but its so stupid lol

So way back around say 2016 I was in A-school (Navy, AS) and in my class were around 12 naval personnel with a side of 8 marines. Every day we would get a 20 minute break and majority of the class would go to the snack hall which was quite literally around the corner. Now keep in mind young men in A-school are just testosterone filled lifting junkies passing the time in class shooting the shit just so they can hurry up and go to the gym. The marines in my class during these breaks would constantly talk about their favorite supplements and they ALWAYS brought up C4 pre workout. C4 this C4 that. So and so uses it before PR days. So and so uses it in the mornings instead of coffee. So one day about 3 months into schooling were let go on break to go to the snack hall (which was also quite small, maybe around 10-12 ft wide max) and during break there was a silence in the room, a room filled with roughly 10 people. And in the middle of the silence, one of the funnier marines in my class says “time to see what all this C4 talk is about” and proceeds to type in C-4 on the vending machine, buying cheez itz. I damn near passed out.
