A guy went to stay at a camp for adults. The owner was showing him around, and said, "You're gonna love it here, especially the barrel behind the restrooms. When you feel the need, stick you're dick in the hole for a blow job."
The next day the guy saw the owner and said, "This place is great. I'm going to use that barrel every day."
The owner said, "Every day except Mondays."
"Why not on Mondays?"
The owner said, "That's your day in the barrel."
