Scrubs:

When Turk is timing a minute for Carla’s pregnancy test on the microwave, the result is negative but due to Turk being a cheapskate he brought a rubbish test that takes three minutes not one. So when Carla’s goes to work Turk finds out she’s actually is pregnant.

Turk tells JD the news and he becomes over-excited and tells everyone around the hospital, not to mention certain family members. JD concocts an elaborate plan to surprise Carla with all her friends congratulating her with gifts and banners even before she knows herself.

When Carla tells Turk that if someone took away the pleasure of her finding out that she’s pregnant, she would have to kill them, it looks like JD’s plan is going to backfire. He has to resort to blackmail to sort the mess out.
