2 Christians are lost in a desert, hungry and thirsty.... So they finally come across a mosque, and guy1 says "I'm going to tell the imam my name is Mohammed so he'll give me free food and drinks." Guy2 says "its not a good idea, I'm gonna tell him my real name." So they enter the mosque and find the imam, and they say their names. Imam says "nice to meet you guy2, please, help yourself to any food or water we have" then he turns to guy1 (Mohammed) and he says, "and you brother, hows Ramadan coming along?"
