Saved by the Bell

Zack (Mark-Paul Gosselaar) and Screech (Dustin Diamond) think they've come up with a cure for zits when an experiment in science backfires. They market and sell the cream to all the students during homecoming week. Kelly (Tiffani Thiessen), who is obsessed with being Homecoming Queen, uses the cream as well. The day of the game, everyone's face temporarily turns maroon. Thankfully, maroon is the school color.
