There are a myriad of Silver Age comics in which red kryptonite caused weird changes in Clark. The rules at that time were that each piece of red-K affected Clark differently, and each piece could only affect him once. (Of course, the rules were bent as needed for the story line of the moment.) The changes were always temporary -- typically lasting for a day or two. Some of the odder changes included him getting a lion's head, an ant's head, and growing incredibly long hair (including facial hair).
Now for our Clark: How about it rendering him mute, or else giving him a really odd, distinctive voice?Making him use Bizarro-like speech? Making his senses so powerful that they debilitate him? Making him disoriented so that he feels dizzy when he is upright and he must remain upside down? Reversing his feelings for people so he hates Lois but considers Lex his best friend? Making him believe he is Batman (or Santa Claus)? Makes him give off a powerful, distinctive (pleasant, but identifiable) scent?
I guess that's enough silliness from me for the moment. Next?
Joy,
