Teamwork. . . . .

A salesman is driving on a two-lane country road in a rainstorm and gets stuck in a ditch. He asks a nearby farmer for help.

The farmer hitches up Elmo, his blind mule, to the salesman's car and hollers, "Pull Sam, pull!" Nothing happens.

He again yells, "Pull Bessie, pull!" Still nothing.

"Pull Jackson, pull!" Still nothing.

Finally he hollers, "Pull Elmo, pull!" and Elmo pulls the car right out of the ditch.

The driver is confused and says, "I don't understand. Why did you have to call out all those names?"

"Look, if he didn't think he had any help, he wouldn't even try!"
