This week Luke and Evan take a break from talking about their favourite meddling kids (and their dumb dog, too) on the ol' idiot box to discussing just two of the teens (no dog) making their way on to the silver screen! But which pair is it, and why isn't it Shaggy and Velma?

The "Scooby Dupe" doesn't come up this episode, so this is as good a place as any to remind you that it's a term the duo have coined for a scenario, typically enacted by Scooby and Shaggy, that holds such great social pressure that the monster chasing them is forced to comply. Never forget.
