we've got a bloke at work that we call Screech - as he looks just like him (well the same type of pubey-looking hair anyway)- big bloke about 6'2 and 15 stone - gets a bit knocky about it for some reason
....and I dunno if he still does it but I saw him doing standup comedy at UCLA and afterwards he just mingles at the bar...well worth going to. He was infinitely better than Richie Twatwood who I saw at Brunel with about 4 people in attendance.
Screech has made a cameo appearance in a couple of movies lately. But I forgot their titles. He's become a bit of a cult figure now, and is milking it for all it's worth. He does stand up comedy too around the USA and takes the piss out of himself, and the character he played. Seems to be doing better than most of the ex-Saved By The Bell cast though.
