Two And A Half Men (2003) - 3x13 - Humiliation is a Visual Medium

No one believes Charlie when he says that his relationship with Mia is getting serious, and everyone really thinks he's lost it when he confesses that they have been dating for more than a month and haven't consummated the relationship. After a continuing series of chaste dates -- walking on the beach, visiting an art gallery, going bowling -- that end with Charlie frustrated at Mia's doorstep, he makes a proposal that threatens their burgeoning romance.
