The 12th incarnation of the Doctor, a timelord from Gallifrey that was created for the television series Doctor Who. When he regenerated (got a new body as a way of cheating death) from the 11th doctor, he exclaimed, "KIDNEYS! I don't like the color."
"Who's that guy over there?"

"That's Peter Capaldi, the newest incarnation of the Doctor."

Get the Peter Capaldi mug.
The reason why all of the Doctor Who fan girls will be leaving the horrendously corrupted audience of the show. He's a dude that doesn't like the color of his kidneys and does not know how to operate the Tardis. Hell, for all we know he could destroy the goddamn thing with his Scottish accent.

Also known as The 12th Doctor by Doctor Who fans.
We all thought that Doctor Who was in perfectly good shape until Peter Capaldi came along and complained about his kidneys.
