Ep 18. Ralph Versus Potsie

In this episode of Happy Days, titled "Ralph Versus Potsie," the gang rallies together for a heated debate.

Ralph, known for always exaggerating his personal achievements, claims to have an IQ of 160, which is higher than Potsie's measured IQ of 155.

As their argument escalates, Richie and the others agree to settle the matter through a series of challenges to test their intelligence. The first challenge is a simple game of chess, which Potsie confidently wins, followed by a spelling bee where Ralph comes out on top.
