S9·E23 The End of the World as We Know It

Kelly and Matt babysit Erin, and have sex in the living room after she goes to sleep. They do not realize that Mel and Jackie have set up a video camera to observe prospective nannies with Erin. Erin switches the tape with a copy of ""There's Something About Mary,"" and the illicit video ends up in Dylan and Gina's hands. Dylan becomes furious, prompting Gina to suspect that he still has feelings for Kelly. She believes that Dylan is trying to overcompensate by arranging a private concert by Monica, and tricks him into admitting that he slept with Kelly in Mexico. Matt breaks up with Kelly, who reminds him that he was married at the time. He forgives her after she insists that she never revealed the truth because she did not want to add to his woes. Donna asks Wayne, a good-looking pro beach volleyball player, to model her new line of men's wear.
