Mean Streak: According to Variety, Paramount Pictures is on a Mean Streak, pre-emptively buying a comedy pitch from Shrek 2 writers J. David Stem and David N. Weiss for Guy Walks Into A Bar partners Jon Berg and Todd Komarnicki to produce.

The story, based on an idea by Berg, centers on an elementary school teacher who's on a field trip to a mock-up of Salem, Mass., on the day he's being dumped by his fiance for being too nice. When he finds himself in a gift shop, a clerk dressed like a witch hears him wish he could be meaner and starts a curse that requires him to retaliate.

"He has to get in touch with his inner demons and find out he's not really as nice as he's tried to be," Weiss said.
