A priest and a nun are off to do missionary work in Japan. They're lending a hand with the cleanup effort after the earthquake, tsunami, and nuclear threats. When they arrive, they realize that they forgot to book accommodations. After checking with every hotel within reasonable distance, they find that only one hotel has one room, that unfortunately has only a single queen sized bed. Since it's the only room available, they take it.
Being an honorable man, the priest offers to sleep on the floor. The nun says, "Father, you may sleep on the bed with me so long as you stay on top of the covers."
"Of course Sister, thank you."
"You are quite welcome, Father."
So the nun gets under the covers while the priest is in the bathroom. The priest comes out and lays on top of the covers.
"Good night, Sister."
"Good night, Father."
A few minutes go by, and the nun speaks, "Father, I'm a bit thirsty. Could you get me a glass of water?"
"Yes, Sister."
The priest gets up and get's the glass of water for the nun who is thankful. After a few more minutes, the nun speaks again. "Father, I'm feeling a bit hungry. In my bag there is an apple. Would you get it for me?"
Sigh "Yes, Sister."
The priest gets up and after a few moments of rummaging through the nun's luggage, he produces an apple from her bag. A few more minutes go by, and the nun speaks again. "Father, I'm a bit cold. Would you get me an extra blanket?"
"Sister, here we are, two adults, sharing a bed. Do you think that just this once, we could pretend to be a married couple? No one would ever have to know."
So the nun thinks about it for a moment, and finally replies. "Yes, Father. I think I might like that."
To which the priest replies. "Great! Now get up and get your own blanket! I'm tired!"
Admit it, you thought this joke was going somewhere that it shouldn't.
