A guy walks up to the "Visa on arrival" counter at the Bangkok International Airport. Presents two Indian passports with 2000 baht cash and says, "Two visas. For me and my wife. Here are the passports and cash". 

The officer at the counter says, "Extra 2000 bahts please". The man asks him' "Why extra?" Says the officer, "We charge corkage for bringing own wife to Thailand."
