Bad day for TV comedy.

Fox on Wednesday pulled the freshman sibling comedy “Ben and Kate,” which had been the weakest player, ratings-wise, in its two-hour Tuesday comedy block. “B&K” was averaging about 3.1 million viewers (factoring in DVR viewing).

Hours earlier, ABC’s “Don’t Trust the B---- in Apt. 23” got the hook. Same reason, except “B---- in Apt. 23” was averaging about 4.5 million viewers — a.k.a. about a million more viewers than watched the unveiling of Oprah’s Lance Armstrong chat last Thursday.

Officially, Fox says that it plans to air its six remaining episodes of “B&K” at some time — but we’ve heard that gag before.

As for “B---- in Apt. 23,” star James Van Der Beek was doing most of the talking Tuesday.

“Sad to say ABC has pulled #Apt23 and will not be airing the 8 remaining episodes any time soon. Translation: we’ve basically been cancelled,” the actor tweeted.

“I know most of you watched us on your own time & platform and that the competitive network scheduling game is irrelevant to you,” he continued via Twitter.

“But network TV is a business dictated by Nielsen ratings. And while that’s an antiquated business model, it’s the only one they’ve got.”
