saw a commercial for a movie - some kind of cheesy horror comedy called Slither
http://www.slithermovie.net/
at the end of both trailers there is some kind of body inflation scene. some chick blows up into a giant ball like in WIlly Wonka. In the trailer you only see her fully inflated, and then she explodes. Its gross, but it looks like something to check out if you dig it...
peace
oh yeah, i saw it on discovery times channel couple minutes ago
