Here's What You Should Do:
The Babysitting Conundrum
The plot revolves around Sheldon being forced to babysit a relative of Penny's. Penny is suddenly called away due to an emergency at the Cheesecake Factory (which would have to change now, since she no longer works there in the show), and has no other option but to ask Sheldon to watch her niece.
Sheldon is, of course, extremely hesitant to assist, but has to concede when Penny points out that, as a friend, he is required to do her this favor.
I mean, just picture the awkward stares between him and the niece. Who wouldn't love that.
Somebody get Chuck Lorre on the phone.
