So this Genie (Ah well) gives one free wish each to Paddy, Mustaffa and Geordie.
Paddy asks for, and gets, all rivers across the water to be Guiness. (Good idea)
Mustaffa asks for a wall around all Muslim and Islamic states, to keep out the Christians, and the Belgians.
Geordie says, "tell me more about this wall, can it be scaled?
"No" said the Genie.
"Can it be burried under?"
"No" said the Genie
"Can we get to fly over it?"
"NO!" insisted the Genie, "No man can ever pass over, under or through it!"
"Ok", said Geordie, "Fill it with water!"
