PEOPLE IN BRIEF: Hanna wards off bears with pepper spray

COLUMBUS, Ohio -- TV host and zookeeper Jack Hanna said he took his own advice and used pepper spray on grizzlies headed toward him.

The Columbus Zoo keeper and frequent David Letterman guest said he was with his wife and other hikers in Montana's Glacier National Park on Saturday when they saw the mother bear and two large cubs coming toward them. Hanna and the others moved slowly back up the trail to a clearing and stood still while the mother and one cub passed by.

Hanna said the other cub, weighing about 125 pounds, charged toward the hikers. Hanna sprayed the bear in the face, and it fled.

Hanna had recently filmed a message for the National Park Service encouraging hikers to carry pepper spray.

NBC affirms Steve Carell's 'Office' exit

LOS ANGELES -- NBC may wish Steve Carell was just joking, but a network executive said ''The Office'' star has consistently told NBC he's leaving after this coming season.

In the network's first acknowledgment of Carell's plans, NBC Primetime Entertainment President Angela Bromstad said Monday the actor's seven-year run as erratic Dunder Mifflin boss Michael Scott will end when his contract expires in 2011. But Bromstad said the show will go on.

In an affirmation of NBC's faith in a post-Carell ''The Office,'' Bromstad said the sitcom will remain in its 9 p.m. Thursday time slot. It's the linchpin of NBC's schedule on a key TV night of advertising revenue.
