Replying to THe "Can Someone define a shot?" thread

over the last few days i've seen a lot of post with people claming to take down 30 shots in one night or 25 in one hour. Heres the problem. If you were actually taking shots that would kill you. i think people need to come clean about how much rum/vodka/etc. is actually in there shot glass. Becasue if your shot is only 1/5 rum/vodka/etc, that means you took 6 shots on the night (which i consider not much at all. so my question to NS is does anyone here actually take straight up shots? And why would anyone want to take a shot thats only 1/5 of acutallly booze.
