Just caught onto this one!

LOVE it!
The options as I see them:
1. There are no Superman costumes left at the store.
2. He tells her he would be uncomfortable wearing tights. (it IS a lot to ask of someone; you should not just assume that someone will wear tights when you tell them to!)
3. He calls her on her CLEAR attraction to him (She is asking him to wear TIGHTS! For Pete's sake!)
4. He stuffs the suit w/ a pillow and reveals to Lois that behind his business suits he hides a potbelly.
