A woman took an inexperienced man home one night. When they got to her apartment, she suggested that they try a 69. "What do you mean?" he asked. Not knowing quite how to explain, she said "you put your head between my legs and I'll put my head between your legs," still unsure but willing, he agreed.
As soon as he got his head between her legs, she let out this rip roaring fart. "What the frigging hell was that?!?" he asked. "Oops! I'm so sorry! Let's try again," she said. On the second attempt the very same thing happened.
The man immediately got up and started getting dressed. "Where are you going?" she asked, to which he replied..."If you think I'm going to stand another 67 of those feckers, you're sadly mistaken!!"
