LIGHT SPOILERS
By far this is one of the top five episodes of this show.
From a routine involving Colin's "hair" and Drew as a gynecologist, to the exchanges between Ryan and Greg, and the hilarious Ryan and Colin failed romance skit with lines written by the audience which turn out to be amazingly accurate and fitting for the scene, the laughs just never stop.
I'm surprised it took 19 episodes to get to Colin's hair, but it finally arrived; fans of "Whose Line Is It Anyway?" have long known the comedic hits that topic has been known to bring.
A strong cast of comedians and no song numbers -- kind of the perfect mix.
