On last night's 30 Rock Liz Lemon's smarmy ex-boyfriend, Dennis, comes back into the picture. Dennis, a beeper salesman/loser/pork-pie-hat-enthusiast, becomes a New York City hero and minor celebrity by saving a stranger from being run over by an oncoming subway car. In the clip above, Liz tries to explain to her coworker, Jenna, why she keeps getting back together with Dennis: because, although she works so hard at everything else in her life, being with Dennis is easy. Jenna responds that love isn't "easy", "It's hiding who you are at all times. It's wearing make up to bed and going downstairs to the Burger King to poop." Swoon!
