they decide a wish each is only fair...
the pom says "i want all muslims, arabs and pakis on an island in the middle of nowhere"
*poof*... "it is done, but you(in reference to the arab) get your wish first"
the arab bloke, obviously not happy about this says "and i want a wall, 100m high so noone can get in"
*poof*.... "it is done"
the aussie sits and thinks for a second, "so all arabs and shit are on some island with a 100 m wall round it..."
"yep" genie replies...
"fill it with water"
