Superboy gets his own trifecta of disturbing moments. Because he's super, don'tcha know.
Hoooookay. A couple of problems here. The first being that he's going to an awful lot of trouble to raise the temperature on a thermometer. I mean, he has heat vision and all. And he rubbed the thermometer with enough friction to fuse it back shut, so he could have just done that to raise the temperature reading in the first place. But even more troubling is that there is now some mercury laying around waiting for another schoolchild to touch it.
Wow. This is easily one of the most disturbing things I've ever seen. I'm surprised those two remaining chickens aren't running for their lives.
No, seriously, Superboy. Just answer the dang question. Not everything has to be an excuse for you to show off.
