One extra deleted scene is one that had been rumoured for quite some time, but now we get to see it - the home appliances (TV, dishwasher, washing machine) in Charlie's house coming alive... with some rough CG animation, as it was obviously cut during post-production.

(most of the scene is actually in the movie, but re-edited in post-production to remove any hint of the appliances)
The exclusive release of the deleted scene can be seen here, while screen-grabs of the appliances can be seen here.
