Charlie Sheen, still talking, '30 Rock,' still airing

So much television, so little time:

— He may already be in the rear-view mirror of CBS’ “Two and a Half Men,” but Charlie Sheen’s still raging against the dying of the limelight, pumping Comedy Central’s 10 p.m. Monday airing of this past weekend’s roast, with stops so far announced on Thursday’s “The Tonight Show with Jay Leno” (11:35 p.m., NBC10) and Monday’s “The Wendy Williams Show” (10 a.m, Fox29).

— NBC’s “30 Rock” is taking a pregnant pause until midseason, in deference to creator/star (and Upper Darby native) Tina Fey — who gave birth to her second daughter last month — but it’s not really going away.  Starting Monday, the Emmy-winning sitcom is in national syndication, with episodes airing at 6 on weeknights on PHL17.

— Making us feel old today: Luke Schroder, son of Rick/Ricky Schroder (“Silver Spoons,” “NYPD Blue”), stars opposite Dean Cain  in “A Mile in His Shoes” (7 p.m. Sept. 25, GMC).

Schroder, who's the second oldest of Rick's four children and whose head shot makes him look a lot like his dad, makes his TV debut as a young baseball player with Asperger’s syndrome who’s recruited to play for a minor-league team.

— PBS Kids is pushing the results of a study published in the journal Pediatrics that found that watching a nine-minute clip of “SpongeBob SquarePants” hurt the attention span of 4-year-olds but that watching a similar clip of  the PBS Kids cartoon “Caillou” didn’t.

Apparently 4-year-olds watching "Caillou" performed as well on tests of their “executive function” afterward as a group that spent those nine minutes drawing pictures.

Good news for parents who’ve invested heavily in crayons and, perhaps, for all those college students in “SpongeBob’s” audience, whose attention spans are probably shot by now, anyway.
