Whose Line is it Anyway?

Song Titles has the four at an office Christmas party. In Duet, Chip and Wayne sing to Lily the Crossing Guard as the Backstreet Boys. In Action Replay, Wayne and Chip are two campers getting dressed in the morning, and discover insects crawled in their clothes. Then, Ryan and Colin perform a different scene using the same body movements. In Greatest Hits, Colin and Ryan sell a compilation album about pregnancy, as sung by Chip and Wayne. No winner is announced, so Wayne, Chip, and Colin sing as a Doo-Wop group about Lola, who died tragicly in a freak golf accident.
