A real virgin
A truck driver pulled over to the side of the road and picked up two homosexuals who were hitchhiking.
They climbed into the cab and the truck driver pulled the rig back onto the highway.
A few minutes later, the first fag said. "Excuse me, but I have to fart."
He held his breath, then the truck driver heard a low "Hsssssss."
A few miles down the road, the second fag announced, "Excuse me, but I have to fart."
The announcement was followed by another low "Hsssssss."
"Jesus Fuckin Christ!" the truckie exclaimed. "You fairies can't even fart like men. Listen to this." A moment later he emitted a deafening staccato machine gun burst from his arse.
"Ohhh!" one fag exclaimed, turning to the other. "You know what we have here, Bruce? A real virgin!"
