"Questionable Impressions" takes a TV-turn, and is set in an emergency room; Brad and Wayne sing a country song "Duet" to Lassie; all four do a "Film Dub" of two fighting street gangs; Ryan is an angel, and Colin is Bosley, and they're trying to save the other angels from a militia headquarters in "Sound Effects".
No one is announced as a winner, but Sid Caesar comes out to play "Foreign Film Dub" with Drew, movie titled "Escargot" and the languages French, German, Japanese, and Russian (Ryan translates for Drew, Colin for Sid, and Wayne calls out language switches).

Whose Line Is It Anyway? Show Summary

Whose Line Is It Anyway? (1998-2004, 2013 - ?) is a continuation of the British show of the same name which aired from 1988 to 1998 with many of the same performers.

It features some of the nation's finest improvisational comedians, including Florida's Wayne Brady, Canada's Colin Mochrie, and Ryan Stiles and Drew Carey from The Drew Carey Show.

Each week, the preceding four and a rotating group of actors and actresses spontaneously played games with outrageous scenes, weird quirks, or (sometimes off-key) songs.
