You'll have to go back to Earth for about a week, but you can't go back as humans. What'll it be?"
The first friend says, "I've always wanted to be an eagle, soaring above the Rocky Mountains."
"So be it," says St. Peter, and off flies the first friend.
The second friend mulls this over for a moment and asks wryly, "Will any of this week 'count', St. Peter?"
"No, I told you the computer's down. There's no way we can keep track of what you're doing."
"In that case," says the second friend, "I've always wanted to be a stud."
"So be it," says St. Peter, and the second friend disappears.
A week goes by, the computer is repaired, and the Lord tells St. Peter to recall the two friends. "Will you have any trouble locating them?" He asks.
"The first one should be easy," says St. Peter. "He's somewhere over the Rockies, flying with the eagles.
But the second one could prove to be more problematic. He's on a snow tire, somewhere in Minnesota."
