Woman calls her husband on the road to warn him, but his response takes the cake

An old man in a Volvo is driving home from work when his wife rings him on his car phone.

"Honey," she says in a worried voice, "be careful. There was a bit on the news just now, some lunatic is driving the wrong way down the freeway."

"It's much worse than that," he replies, "there are hundreds of them!"
