That by itself is creepy. Why on Earth would he even think of doing something like that? Who ever would?
It gets worse, however. From the Lex Luthor article at Wikipedia (emphasis mine):
[As a young man] Lex Luthor is shown as an aspiring scientist who resides in Smallville, the hometown of Superboy. The teenage Luthor saves Superboy from a chance encounter with Kryptonite. In gratitude Superboy builds Luthor a laboratory… Grateful in turn to Superboy, Luthor creates an antidote for Kryptonite poisoning. However, an accidental fire breaks out in Luthor’s lab. Superboy uses his super-breath to extinguish the flames, inadvertently spilling chemicals which cause Luthor to go bald…
In other words, Superboy has a souvineor from an accident that he is in part to blame for. One that resulted in creating a mad scientist that caused more than a few massacres in his time.
Clark, y’know I’m a fan, but that? That ain’t right. You might wanna talk to someone about that.
