The Big Bang Theory Episode 2.09 The White Asparagus Triangulation

Leonard continues to date Stephanie and things seem to be going well as far as he's concerned. Sheldon, however, is worried that Leonard isn't handling things correctly; Sheldon really likes Stephanie and it's extremely important to him that Leonard's relationship go well. At first he seeks Penny's perspective on Leonard's relationship deficiencies, then orchestrates things to make Leonard seem more manly. When this backfires, he decides to hack Leonard's Facebook page, and change Leonard's relationship status to "in a relationship." Leonard's furious that Sheldon has forced him into the cyber-equivalent of saying "I love you" first, but when Stephanie reciprocates, all ends well.
