Bumping and grinding, beautifying and geeking…reality rules tonight. Be sure to tune in and enjoy the last great night of television before the weekend doldrums start.

Dancing With the Stars, 8pm, ABC. This special 90 minute episode will satisfy your celebreality needs. Just be sure to tape Beauty and the Geek.

Grease 2, 8pm, TBS. This isn’t exactly stellar prime time material, but we have a soft spot for this Michelle Pfeiffer early-1980s debut.

That 70s Show, 8:30, FOX. One of the last new episodes ever, as the series will soon sign off.

The O.C., 9pm, FOX. Money and melodrama highlight the adventures of Brandon and Dylan and Kelly…er, of Marissa and Summer and Seth.

My Name is Earl, 9pm, NBC. Everybody’s favorite hillbilly is shining in his new time spot.

Beauty and the Geek, 9pm, the WB. Oh, how we love this show. Love and trouble are already brewing, and it’s only the second episode!

True Life, 10pm, MTV. Tonight, extreme sportists explain why they have a death wish.

The Fog, 11pm, SciFi. The original is worth catching, if just to erase the hideous memories of the remake from your mind.
