Blonde and the Western

A blonde and her husband are laying in bed watching TV, an old western is on. The husband says to his wife:

- I bet you breakfast in bed that the covered wagon hits a rock and the driver falls out dead,

- You're on - returned his wife.

They watch the western and sure enough the wagon hits a rock in the dirt road and the driver falls out of the wagon ... dead. The wife gets out of bed and returns shortly with a tray of food. After eating the husband says:

- I have to admit that I saw this movie before.

She in turn confesses:

- I saw the movie before too. But I didn't think he was stupid enough to ride over the same rock twice....
