Cronkite out for good Cos

NEW YORK — Bill Cosby has come to the rescue of another CBS daypart.

The Cos — whose self-titled Monday sitcom and Friday night reality half-hour “Kids Say the Darndest Things” are both solid Nielsen performers for the Eye — helped save the day on the web’s “This Morning” Tuesday after scheduled guest Walter Cronkite had to bail out of a scheduled appearance on the ayem broadcast at the last minute.

According to a CBS News spokeswoman, Cronkite was en route to the CBS Broadcast Center when he suddenly felt ill and asked to be taken to a nearby hospital. His reps called about 30 minutes before his appearance to let the producers of “This Morning” know Uncle Walter would be a no-show.

While all this was taking place, Cosby — scheduled to appear after Cronkite on Tuesday’s “This Morning” — was bonding with another guest: Martha Stewart, the ayem show’s domestic diva in residence. The two were having so much pre-show fun that Stewart asked Cosby to do a walk-on during her scheduled segment on ironing shirts.

Cosby and Stewart got along so well on-air that producers extended Stewart’s segment, easily filling the gap created by Cronkite’s unanticipated absence. And Cronkite? He’s back home and “doing fine,” a CBS spokeswoman said.
