Season 5, Episode 8
When Bart & Milhouse find a $20 bill in the street they spend it wisely - on a 100% syrup squishy at the Kwik-E-Mart. However, the taste leaves them to have some weird side effects and during their out-of-character state of mind Bart ends up joining a scouts club run by Ned Flanders.
There are references to Deliverance and Crocodile Dundee.
