@Wanda: I originally thought of getting myself a Superman t-shirt as well, but I teach in a university and the professors' dress code (at least for us younger ones) will not allow for it because they didn't want us looking like the kids. My necklace is a good compromise. ^_^'
I also bought outfits for work that bear striking resemblances to ones Lois wore in S1-S2 before they started sticking her into all those unfeminine pantsuits. I get to cosplay as Lois Lane every day!
Here is a pic of my necklace. Would you guys mind posting pictures of your knick-knacks? I would really love to see them.
