Scruffy had been digging gold for 30 years, when he decided to go to town for nookie.

In the town brothel he was assigned to Maria Lopez, who explained that sex had changed allot in the last 3 decades.

She introduced him to a new technique called "69".
A minute into it, Maria broke wind, causing Scruffy to jump out of bed while wiping off his nose.

Maria got scruffy back into position, but after a minute, she broke wind again and Scruffy leaped out of bed and started putting his clothes on.

Maria asked his where he thought he was going.
Scruffy answered, "I can't take THAT 67 more times."
