On Dawson's Creek (8 p.m., WB), everybody cuts class on senior Ditch Day -- everybody except Pacey. NBC is jiggering the schedule to cram another episode of Weakest Link in at 10 p.m., so The West Wing (8 p.m., NBC) airs an hour earlier than normal. It's a rerun of the one where Toby is screwed over by the majority leader's new chief of staff (Felicity Huffman). There's also a subplot about Donna losing her panties at a big media gathering that seemed really weird the first time around. But in light of Aaron Sorkin's recent drug bust, it all makes sense: It was the magic mushrooms talking. American Masters (8:30 p.m., PBS, check local times) presents "A Conversation With Gregory Peck," director Barbara Kopple's portrait of the veteran actor as he looks back on his life and career. Felicity (9 p.m., WB) returns from its long hiatus and picks up where it left off: Who got shot at Felicity's Christmas party? The Job (9:30 p.m., ABC) airs its last episode; there's no word yet on whether it will be back next season. McNeil is ordered to attend anger management classes. On Once & Again (10 p.m., ABC), Rick feels the heat from the Atlantor investigation, and it brings up a chilling memory.
