Gag (2006)

Two thieves break into a seemingly empty house hoping to find loot, but instead of booty they discover a brutally beaten bloke tied to a torn mattress. Deciding to do a good deed, the cursed crooks of Gag (2006) throw out their pilfering plans and try to help the fella, only to realize too late that they should have minded their own business. Drat, it was a trap! Before long, the two are getting tortured but good by a really, really bad dude. He makes them swallow various foreign objects, jabs them in the hoo-hah with spears, and even sics rodents on them, which is torture not only to the burglars, but to PETA as well! Gag leaves no victim spared.
