no saliva needed

SK and i were addressing an envelope with checks for our friend's birthday gift. we still have the superhero stamps (worth $0.39). so of course, since postage has gone up, i bought a bunch of $0.01 stamps to bring up the postage to the required $0.41. just now, i walk into SK's room, only to here her say, "these stamps don't stick very well" immediately followed by seeing her lick the back of the stamp. i've just watched her lick the paper sticker backing. i start laughing and fall onto the floor, which causes her to come to the realization that she's just licked the paper backing to self-adhesive stamps. so awesome.
