Two And A Half Men: Season 8, Episode 10

8 - 10: Ow, Ow, Don't Stop

When Courtney (last seen going to prison in "Fish in a Drawer") returns, Charlie gets back together with her. However, she takes advantage of him, making him go on limitless spending sprees for her and injuring him during sex. Eventually, Charlie realizes she is just using him and they break up. But later, after talking with Alan on the deck, Charlie decides to chase after her and get her back, crashing through the glass back door in the process. The episode ends with Courtney visiting Charlie in the hospital, and Charlie shallowly declaring his love for her again. Title quotation from: Charlie, covered in lacerations after crashing through a glass door, being kissed by Courtney
