A gay couple (Jeremiah and Timothy) is traveling on a plane.
"What if we had sex?" asks Jeremiah.
"Are you crazy? Here, on the plane? It would be awkward, everyone would watch us doing it..."
"Nobody is even paying attention to anything. Look!"
Jeremiah stands up and asks loudly:
"Could I have a napkin, please?"
Nobody gives a damn. Everyone is sleeping, reading, looking out the window, etc. Flight attendants pretend to not hear them, as they also don't give a damn.
"They really wouldn't care then, would they?" says Timothy.
So Jeremiah and Timothy have wild sex on the plane.
Later, when the plane arrives to the airport and the people are leaving, the stewardess sees an old man who threw up all over his shirt, even his pants are soaking in the filth.
"Sir, you should've asked for a bag!"
"I didn't dare" whispers the old man. "A few rows ahead I saw a man asking for a napkin and he got fucked in the ass..."
