1x12 - Archie's Weird Mysteries

Moose's trouble with school work leads him to employ the use of Dilton's new invention, a helmet which seems to make him miraculously smart. But Moose soon becomes addicted to his new brains and keeps secretly using the machine, which grants him telekenises along with a dangerous angry streak -- and he leaves behind friends, football, and a heart-broken Midge in the process.
