With REO Speedwagon in town for a concert, Calvin is delighted that Dave likes the band so that he can take Tina in Calvin's place. When someone mistakes Dave and Tina for a married couple at the show, Tina laughs and says that could never happen, hurting Dave's feelings. She tells him they are just too different, and she's not talking about color. At home, Calvin and Malcolm try to help Gemma rid her house of a wild parrot that flew in. Meanwhile, Marty scares Grover as they watch a meteor shower, saying that one could hit the earth at any time and cause a major catastrophe.

With Calvin down a teammate for his annual bowling championship, Dave offers to fill in and soon finds his mediation skills put to the test when he meets the competition: Calvin's arch-rivals, the Pink Ladies. Also, Gemma and Tina dare to face off against each other for the top ranking in an arcade game.
