Wednesday's Best Bets on TV

“The Baby Borrowers” (9 p.m., NBC): The overwhelmed teens of “The Baby Borrowers” have dealt with infants and toddlers and teens. Now, as the reality series comes to an end, they’re faced with one more challenge: caring for elderly folks. Our guess is they won’t be in a rush to become parents any time soon. Preceded by a separate episode at 8 p.m. “House of Payne” (9 p.m., TBS): On “House of Payne,” Curtis’ father drops by to meet Calvin’s fianc e, but it seems that he’s already met her before and it didn’t exactly end happily. Two more new episodes follow.
