This season two episode is amazing, and it's not just because of a shirtless Justin Theroux (but he helps). Carrie finds herself dating Vaughn Wysel, a writer with amazing parents. There's only one problem: premature ejaculation. Carrie debates staying in the relationship because she's that obsessed with the man's family, but by the end of it, she's forced to break up with him . . . and his mother. Valerie Harper plays the mother (and owns the role), and the episode is truly cringeworthy in that amazing way that only "Sex and the City" can pull off.
