MIA COMES BACK IN TOWN WITH AN UNEXPECTED QUESTION FOR CHARLIE, AND CHARLIE POPS AN UNEXPECTED QUESTION OF HIS OWN, ON PART ONE OF A TWO-PART SEASON FINALE OF "TWO AND A HALF MEN," MONDAY, MAY 15

Emmanuelle Vaugier ("Saw II") Guest Stars

"Arguments for the Quickie" -- Charlie's ex-girlfriend, Mia, comes back in town with an unexpected request, which Charlie follows with an unexpected question of his own, on part one of a two-part season finale of TWO AND A HALF MEN, Monday, May 15 (9:00-9:30 PM, ET/PT), on the CBS Television Network. Jamie Widdoes directed the episode from a story by Susan Beavers and Don Foster, and a teleplay by Chuck Lorre and Lee Aronsohn, two of the series' executive producers.

Emmanuelle Vaugier ("Saw II") guest stars in the episode, making her fifth appearance on the series as Mia, Charlie's ex-girlfriend.

When Charlie finds out that Mia is in town with her dance troupe and has invited him to her performance, he opts not to go and tries to convince Alan (and himself) that he's over her. After surprising Alan (and himself) by showing up, Charlie gets another surprise when Mia explains that she wants something personal from him -- his sperm. Shockingly, commitment-phobic Charlie responds by asking Mia for something as well.
