Mandy Patinkin alert: The camera-shy (not!) star of "Chicago Hope" works for old boss David E. Kelley again in the season finale of Boston Public (8 p.m., Fox). He plays a pushy parent who wants his home-schooled kid to take part in Winslow's graduation ceremony. Carrie might be pregnant on the one-hour season finale of The King of Queens (8 p.m., CBS). Sisters Mary and Lucy have it out over Lucy's fiancé on the season-ending 7th Heaven (8 p.m., WB). Everybody Loves Raymond (9 p.m., CBS) stacks two episodes back to back and calls it a season finale. In the second one (9:30), Ray flashes back to the day Debra gave birth to Ally. In the season finale of Roswell (9 p.m., WB), the alien kids have just 24 hours to say goodbye to their Earth friends before blasting off for home. Actually, they're blasting off for UPN, which, ratings-wise, might as well be Pluto. UPN snapped up the cult fave series after the WB dumped it; it will air on Tuesdays at 9 -- following "Buffy" -- next fall. Ally nurses her broken heart by attending a high school prom (ladies and gentlemen, K.C. and the Sunshine Band are in the house!) on the season finale of Ally McBeal (9 p.m., Fox). Third Watch (10 p.m., NBC) ends its season by becoming the third NBC series in the past week (after "Law & Order" and "ER") to build a story around a mass shooting involving children.
Sugar Ray's Mark McGrath hosts a five-part countdown of the 100 Most Shocking Moments in Rock and Roll (10 p.m., VH1). Where were you when you heard the news that Duran Duran were making a comeback?
