Roommate: "Dude...what is that on your head?"
Me: "It's a fez. I wear a fez now. Fezzes are cool."
Roommate: "That is not a fez. It is a lampshade."
Me: "That's because it's a Psychic Fez- like Psychic Paper, but in fez form. It disguises itself as something like a fez, but not actually a fez. Unless you're psychic. Then it just looks like a fez. Which it is. A psychic fez. It's cool."
Roommate: "....you are the most awesomely weird person that I know."
Me: "Of course I am. I'm The Doctor"
