Three couples went out camping. The three husbands stayed in one tent and the three wives stayed in the other. At about 3 in the morning, Bob woke up and yelled, "Wow, unbelievable!"

Bill woke up and asked, "What's going on?"

Bob said, "I've got to go to the other tent and find my wife."

"How come?"

"To have sex! I just woke up with the biggest hard-on I've ever had in my life!"

After a pause, Bill said, "Do you want me to come with you?"

"Hell, no! Why would I want you to do that?"
