SpongeBob SquarePants (3-8 p.m., Nick): It's a five-hour minimarathon of episodes that revolve around the rivalry between Mr. Krabs and Plankton. At 6 p.m., there's a new installment that flashes back to their childhood, when the two bitter enemies were best friends!

Stargate SG-1 (6 and 9 p.m., Sci Fi) and Stargate Atlantis (7 and 10 p.m., Sci Fi): Both shows return from hiatus and wrap up the cliffhangers they left us with. On "SG-1" — which is headed toward a series finale — Adria and her Ori army are closing in on our heroes. And on "Atlantis," Sheppard mounts a rescue mission to free O'Neill and Woosley.

NBA (6:30 p.m., Ch. 14): Jazz at Mavericks

The Riches (10 p.m.-3 a.m., FX): If you missed the first five episodes of this new series about a family of con artists who assume the identities of a rich family, take note. All you have to do is stay up REALLY late or set your VCR/DVR and catch up. Episode 6 airs Monday at 11 p.m.
