Well... he can't be Christian Slater... because I am Christian Slater. And dude, if you are infatuated with me, you're barking up the wrong tree.
However, you can show your appreciation by buying my movies. Royalties are the cat's ass.
To answer the question...
If I woke up next to Charlize Theron or some other exceptionally beautiful woman... I'd wonder who slipped me the hallucinogen, and when it was going
to wear off. I would then calm myself down. Get dressed and sit in a corner until everything became clear.
If it lasted longer than 12 hours, I would pinch myself. If I still didn't wake up, I would then call the Ghost Busters.
