Take away his vicodin
Take away his cane
When you give him back his cane, make sure it's pink and sparkly
Mimic the way he walks
Put his boxers in Cuddy's office
When he's sleeping, put a pink tutu on him.
Tell him it's not Lupus
Show him FF
Show him FF that pair him up with Wilson
Tell him he's a bad doctor
Hug him
Then kiss him
And run, denying you did anything
Poke him constantly
Sing "The Song That Never Ends" as loud as you can when he's near
Write him love letters, and make sure it looks like Wilson wrote them
Throw water balloons at him
Lock him in a room with Cuddy
Vandalize his motorcycle
Replace his vicodin with viagra
