Both awesome!! I like Chakram's suggestion of it being Oolong Tea. Maybe adding a the little tag/string to the mug with "Oolong Tea" on it? It could also be fun to add some other "easter eggs" to it, which would still keep it more or less non-fandom specific. Like maybe having only the LOIS&CLARK keys on the keyboard labeled?
As for the slogan. I'm cool with just the "It's a fanfic thing." (I do want to nitpick because I'm an editor and it's niggling at me... the fanfic shouldn't be capitalized.
I know this isn't the final mockup, though, and I'm open to hearing other opinions if people want it capitalized. :))
Thanks so much KK and hubby!
