Jacob Two-Two (2003)

The school superintendent has shut down the school's decrepit gymnasium, and the only way to get it reopened is to sell a record number of candy bars in the school fundraising drive. Jacob spearheads the effort, encouraging his fellow students to get out there and sell, sell, sell! When he hits the street, however, Jacob finds out that it's not so easy selling to complete strangers, especially when your last house is the haunted abode of a notorious mad scientist!
