152

152 is a minor character in "People I Know"

His real name is unknown, with the joke being that he is called by others just "152" or similarly. This comes from his first appearance, where the Mensa Guy called everyone by the IQ points they have earned.

He has appeared a lot through season 1 in the background, but he appears less in the latter, although having bigger roles. This has to do with the animators learning to add random people in the background instead.

He started to appear in the Opening sequence since episode 2x13.
