The second time I ever got stoned, my friend was all like "Dude! Let's just make a bong out of some old Pepsi bottle!". I don't think I'll ever live it down, but I actually asked "What's a bong?". Then when we were high, I said "I still don't understand how the fuck a bong works, but I like it!".

Arguably 2 of the stupidest things I've ever said.
