Freshman year of college...
My friend had just got back from the mall with his mom who was there for parents weekend. She bought him some clothes and a brand new yankees fitted which he was wearing at the time.
We went outside to smoke hookah and this clown decided he was going to take the biggest hit he could and zero it. He took like a minute long hit and closed his mouth right after. Let no smoke out of his nose or anything. Then...his eyes rolled back into his head and he collapsed. Fell head first onto the coal sitting on top of the hookah. The coal burnt a hole through the side of his fitted and burned his hair slightly. We picked him up off the ground and brushed his head off and he had no idea what happened. If it wasn't for his mom buying him that fitted dude would have had a permanent patch/scar on the side of his head.
It was one of those scary at first/hilarious after he was ok situations...similar to the time I ghost rode my whip and my passenger didn't fully commit... but that's another story.
