You Can't Do That on Television (1979)
S3E3 Popularity
The Most Popular Kids Show on Television will take a brief pause for a special announcement... Ross organizes a "phone-in" contest to determine the most beloved cast member. Each kid sports a number for viewers to cast their votes. Midway through, Kevin, sporting number 111, is leading the pack. In a bid to boost her chances, Christine swaps her number (872) for a more favorable one, 0. Ultimately, Zilch (Darryl) emerges as the winner, despite not being featured in the episode. The revelation comes that Christine's number zero was key to his victory.
