Much of our TV viewing is habitual, especially when it comes to reruns like "Seinfeld."

So when schedules change unexpectedly, there's a disruption, like the one that's sure to come Monday at 6:30, when Channel 6 moves the fast-paced "TMZ" gossip show into the Monday-Friday post-evening news slot. The weekend schedule remains unchanged.

That displaces "Seinfeld" from its long-time weeknight home. Starting Monday, you'll still find the show about nothing at 10:35 weeknights. The second airing will come at 11:35 p.m.

Of course, in our modern DVR era, you could always record the later episodes and watch them whenever you want. And, for the record, TBS airs an hour of "Seinfeld" at 6 p.m. weeknights.

TV's all about the numbers, and the May sweeps period shows how the 6:30 half-hour shakes out.

Nielsen Media Research numbers show Channel 12's airing of "Entertainment Tonight" in the lead with nearly 60,000 households, a 13 percent share of the audience. Channel 58's "Wheel of Fortune" in second with more than 54,000 area households, a 12 percent share.

Since "Wheel" brings in a really old audience -- which isn't as desirable to advertisers -- Channel 12's lead at 6:30 is even more commanding.

After the top two, things drop even more precipitously.

"Two and a Half Men" reruns on Channel 18 averaged almost 34,500 households, a 7 percent share, Channel 4's newscast had nearly 24,500 households, a 5 share.

"Seinfeld" pops up in fifth place, with almost 21,000 households, and a 5 share -- a dip from May 2009 when it had almost 32,600 homes, a 7 share.

Coming in sixth is Channel 24's "Family Guy" rerun, with around 18,000 homes, a 4 share.

Connie goes Fish-less: They've been displaced, at least temporarily, from WQBW-FM (97.3) the radio station formerly known as The Brew. But the Connie and Fish morning show has been continuing this week on Madison's WZEE-FM.

"Fish" announced on the air at 7:20 this morning that he's leaving the radio business as of Friday, and Connie goes solo as of Monday.

There's now a Radio Connie Facebook page, if you're interested.

Yesterday, Kerry Wolfe, operations manager of WQBW-FM, told me it was "very likely" the Connie and Fish morning show would return, once the new top-40 format settles in.

Meanwhile, the other Milwaukee radio station that dumped its format, formerly smooth jazz WJZX-FM (106.9), continued playing an endless string of Beatles songs this morning with no word on what format it will end up with.

On TV: The May cable numbers are out, with the Nielsen stats showing the top five basic cable channels in prime-time are USA, TNT, ESPN, Fox News and Nick-at-Nite.

• While Fox News' strong numbers aren't especially surprising news -- except maybe Neil Cavuto's 100th month at the top of his time period -- CNN's continuing dip is. Larry King had his worst month of the year, averaging some 653,000 viewers at 8 p.m.
• Turner Classic Movies salutes the late Dennis Hopper on June 8 with a marathon of his movies beginning at 7 with 1965's "The Sons of Katie Elder," and 1969's "True Grit" at 9:15, both starring John Wayne. James Dean's 1955 "Rebel Without a Cause" airs at 11:30, followed by 1969's "Easy Rider" at 1:30 a.m., and 1963's "Night Tide" at 3:15 a.m.
• The latest Facebook petition wants George "Mr. Sulu" Takei to host "Saturday Night Live."

A 10 p.m. preview: Comedy Central's Jon Stewart and Stephen Colbert took on Conan O'Brien in a dance-off this week in New York. It sort of pre-figures this fall's premiere of O'Brien on TBS opposite the hour of Stewart and Colbert.
