from wikipedia:

"The Needlers: The Couple That Should Be Divorced" is a recurring skit on Saturday Night Live. Seth Meyers and Amy Poehler portray Dan and Sally Needler, a couple who spends every waking second arguing (needling each other). Why they will not get a divorce is beyond the rational reasoning of anyone.

During the skits, the Needlers (previously known as the Harrisons) constantly argue, and other characters often bring up the question of marriage counseling. The skits invariably end with Dan and Sally having sexual intercourse in public (in the kitchen, in a closet, in a waiting room, etc.).
