Two middle-aged couples go on a camping trip. The men stay in one tent and the women stay in the other. At about two in the morning one man wakes up and says, "Oh my gosh!" The other guy wakes up and asks, "What's wrong?" The man says, "I gotta go find my wife, I just woke up with the biggest e***ction I've ever had!!!" " Want me to come with you?" asks the other guy? " Why would you do that?" "Because you're holding my d--k."
