The Expensive Wipe

Two hunters are walking in the woods when one of them needs to go to the bathroom.

"Go in the bushes," says his friend. "But I don't have any toilet paper!" the first hunter replies. "Just use a dollar bill," the friend suggests. A few minutes later, the hunter returns with messy hands. "What happened?" asks the friend. "I didn't have a dollar bill," the hunter replies, "so I used four quarters."
