Maniac Mansion - Season 3 Episode 11 The Science Fair

Ike is preparing for the science fair and asks Fred for help. Casey and Fred agree that Ike should do it on his own. Then the Pratts want Fred to help Keifer with his project. They at first say no because of Ike, but eventually give in. Fred felt it was unfair to Ike, so he gave him and idea about a project and let Ike do the rest. Since Fred did Keifer's project for him, he couldn't demonstrate it correctly at the fair and failed. Ike's volcano did come in second place, beat only because a girl named Cindy's had a much larger explosion.
