As seen on: Saved By the Bell (NBC)
Portrayed by: Dustin Diamond

Screech never seemed to know what was going on, an aloofness that produced some laughs every now and then. But he was in full quirk mode, charged up at a thousand watt, at all times. It got tiresome.

Example Screech-driven Saved by the Bell plot: Screech promises he knows some baller volleyball players, but, in the end, he brings you an 85-year-old woman, a four-year-old girl in pre-school (whom he paid with a lollipop, we didn't make this up), and a dude nicknamed Big Pete who turned out to be, surprise, skinny and fragile. You got us, Screech. Again. Now go work on a science project and stop killing Zack Morris' vibe.
