The Big Bang Theory

Recap

Leonard is still dating Stephanie, but Sheldon is concerned that Leonard isn't handling things right and decides to help.  Why?  Because of all of Leonard's potential mates, Stephanie is Sheldon's favorite.  At first he seeks Penny's help, whether it's through trying to engage in casual conversation or by bringing her various fruit breads.  When Penny proves to be no help, and after annoying them on a date, Sheldon does some research online and figures out he should establish Leonard as the alpha male.

Sheldon  sets up a scenario where he needs Leonard's help in opening a jar of white asparagus.  However, when Leonard tries to help him open he he cracks the glass and ends up needing stitches.  Stephanie helps stitch him back up, but not without Leonard crying.  Sheldon takes the next step by hacking into Leonard's Facebook account and switching them into "in a relationship."  Leonard is concerned that he's going to seem needy since he requested first, but when Stephanie updates her profile, all is good.
