No lifeguard on duty.

Two frenchmen and an englishman find a lamp and they rub it. The genie pops out and grants them one wish each.

Jaques is very patriotic, and says to the genie "I am worried about attacks on la France from our neighbours. I want a 20 foot high wall all around her borders." Paf! The Genie makes it so.

Next it's Pierres turn "I am still worried about attacks on la France from the air. Put a roof over the whole of her." Paf! And again the genie makes it so.

Jack, the English guy thinks for a minute, takes a sip of his beer and says to the genie, "Fill it with water."
