Rachel reluctantly agrees to be maid of honor at her ex-fiancé Barry's wedding, but steals the couple's thunder when she walks up the aisle with her butt showing. She is even angrier to find out that when she dumped Barry at the altar, his parents told everyone that she ran away because she was insane and that she had syphilis. Ross tries fixing this at the reception but fails. Rachel is about to leave, but doesn't when she learns that Barry was betting on her to leave before 9:45. She tells Barry that she promised herself she'd make it through at least one of his weddings.
