POCATELLO, Idaho (AP) _ Richard Sagness has a double-dipped career - during the school year he's a college professor but during the summer he's a scooper.

That's why they call him Dr. Ice Cream.

''It's a real tough way to spend the summer,'' Sagness chuckled as he leaned over his ice cream cart at downtown Pocatello's Simplot Square. ''I suppose some people think it's beneath my dignity to be doing this, but I think that's nonsense.''

Sagness, who trains the teachers of tomorrow as a professor in Idaho State University's College of Education, says he's not in it for the money. He does it, he says, to help his wife keep her cool.

''He's doing this very willingly,'' maintained Donna Sagness, who owns the local ice cream shop. But she conceded the cart has been a good way to keep her husband out of trouble.

''He's worth what I pay him, which is nothing,'' she said. ''He's good with the cart, but we have to watch him when he's in the store. He'll eat everything, including the flavors that nobody else will eat, like brandied fruitcake.''

Sagness admits his love of ice cream, especially when it's free, keeps him on the job.

''When I was a kid, I worked at a soda fountain. The owner said, 'Eat all you want, because eventually you'll get tired of it,''' he recalled. ''I was his only employee that never got tired of it.''
