Camping by the Colorado River, a woman was surprised to see a man rowing down the river screaming, "No! No! No!" Spotting another woman down the shore, she ran over.

"Say," she said quickly, "shouldn't we do something to help that man? He seems to be in distress."

The other woman looked up, her expression placid. "Oh, he's my husband, and he's just fine."

"If he's fine, then why is he rowing down the river screaming 'no'?"

The other woman smiled. "During the week he's a corporate 'yes' man."
