1x23 - Beverly Hills Teens

Chester invents a love potion as a way to get girls to like him. When Bianca overhears this, she comes up with a plan to use it on Troy so that he will fall in love with her. But a big chaos of events causes all the wrong people to fall in love with each other. Instead of troy chasing Bianca, Bianca is now chasing Wilshire (who is not thrilled with this love-obsessed Bianca).
