“The Simpsons: The Complete Twentieth Season” (20th Century Fox, 2008-09, $59.99): Creator Matt Groening’s animated classic continues to roll along.

This past fall, it became one of the longest continuous-running shows in prime-time TV history, passing the 20-year record of “Gunsmoke.” Using a middle-class family in an offbeat town as its anchors, the series has managed to serve up numerous satiric moments while providing plenty of laughs.

Here’s to Homer, Marge, Bart, Lisa, Maggie and the rest of the town; may they hang around for another 20. This collection includes 21 episodes on two discs.
