Mullah Nasrudin used to cross the border between Anatolia and Persia by a well-known smuggling route, mounted on a donkey.
Stopped by customs guards, he was searched, but they found nothing.
And every time he passed them, on a donkey, he was searched and they never found anything.
So the furious guards asked, "What are you doing here Mullah?"
And he replied: " I'm smuggling!".
Time passed, and now rich with his contraband, Mullah Nasrudin moved to Egypt.
