My sister once employed a guy who constantly claimed he was from Malta and that his name waas Fabio. He always "forgot" to bring his documents in order to be registered.
He constantly tried to tell me Jews and Christians were wrong but not condemned if they regretted and became Muslim.
Well, once, I answered "Okay, Mohammad, what is your freakin' point. If you have problems, don't work in Judeo-Christian business and go beack to TUNISIA, where you REALLY come from."
After 2 weeks he still hadn't brought his documents and my sister called the police. And bet: His name was REALLY MUHAMMAD and he REALLY was from TUNISIA!!!!
