Two gay men are hitchhiking on this highway....They are walking along when a semi stops and offers them a ride.

They get in and introduce themselves.

The drive along pleasantly when all of a sudden one of the gay guys fart. It wasnt the usual loud type but a silent puff of air.

No one says anything and the go along for a while longer.

The second gay guy also lets out a fart....and again its a silent puff of air.

The two guys do this repeatedly until the truck driver says, "Thats not how you fart...this is a real fart!"
And he lets it rip with the sound echoing inside of the trucks cabin.

The two gay guys look at each other and say "Virgin."
