c'mon, some things you know are patently stupid but do anyways. I enjoy licking knives if they have somethign tasty on 'em. Like for cutting up chunks of frozen fruit into manageable pieces, then licking it. especially fun if it's serrated, because I'm an idiot with serrated knives and yes, I also enjoy drinking too much, though I certainly don't enjoy the hangover the next day or throwing up all night
pickin my teeth with knives, cuttin fingernails with razorblades,..... n a myriad of other things i spose...
when i get rrelly stoned, i like to eat to the point where i'm uncomfortable. then i inevitably regret it.
