Three guys go to heaven

Three guys die and end up at the gates of heaven, talking to St. Peter.
"So," Peter asks the first guy, "how many times did you cheat on your wife?"
"None. I had a perfect marriage."
"Great," says Peter. "You get to cruise around heaven in a Mercedes. And you, how many times did you cheat on your wife?"

"Only twice, I think," says the second guy. "Okay. You get to cruise around heaven in a Cadillac. And you, how many times did you cheat on your wife?"
"12 times. Maybe 13," says the third guy.
"Okay," says Peter. "You get a rusty Ford."
Later that day, the guy in the Cadillac sees the guy in the Mercedes crying.
"What's wrong?"
"I just saw my wife."
"So?"
"She was riding a skateboard."
