Who am I and what have I done to the real Calle?

It's a little after 10AM. So far today, I've been to the gym for a workout and I've donated blood.

(And now it seems I'm getting a migraine attack for my troubles. Oh well.)

Give me the brain...!

Because of the migraine I have the attention span of a retarded fruitfly, and can only work in short intervals. I need something to distract me in between. If you give me a pairing (from any of the fandoms I usually wibble about) and a concept, I'll try writing a drabble for it.
