Lois: Can't breathe... getting... weaker... Tempus... must have... gone back... exposed my... younger self... to... ultranite...

Clark: Uh, Lois? You were only Ultra Woman for, like, two days. It doesn't work that way. And there's no such thing as "ultranite."

Lois: Clark... ... *sigh* Fine... It's ragweed... Happy? ... Can't you... at least... let me have... some fun... with my... allergies?

Clark: Sorry. "Ultranite" it is.

When in doubt, think about penguins. It probably won't help, but at least it'll be fun.
