Two Muslims are wandering, starving and lost in the desert- they come across a monastery, and decide to go and ask for hospitality. One said to the other, "I'm going to tell them my name's John, because they're sure to treat me better if they think I'm Christian." His companion replied "I'm going to tell them the truth." They knock on the door of the monastery and a monk opens it. The monk says "My, but you look exhausted. Who do I have the honor of welcoming?" The first man says "I'm John." His companion says "My name's Ahmed." The monk replies "Well Ahmed, let me show you to the kitchen and we'll get you some food. And John, of course, you know that we're fasting today."
