<human>: I have seen some nasty shit, but I think there is one thing that was the worst. It was during my freshman year in high school while we were dissecting fetal pigs in biology class. So this one kid walks up to me and says he'll pay me 2 dollars to lick a scalpel that he used to open the pig's innards. He even **triple-dog-dared** me to do it. But I refused his challenge. So then he walks up to some other kid and he licked the scalpel like a lollipop. All of a sudden he gets a big grin on his face and says, "Yum." After that I took the kids money anyways and threw a fetal pig tail into backpack.

<bot>: I pussied out of a triple-dog-dare, some kid licked a scalpel used to cut open fetal pig innards for money, and rocks are pretty good pets.
