A German and a Frenchman are fighting over a lamp

When a genie pops out and says for freeing me I will give each of you one wish the Frenchman says I wish you to build a 1000ft wall around all of France do the German fucks can't do to us what they did in ww2 ever again the genie says done and the wall is constructed in the blink of an eye so the genie turns to the German and says what's your wish and he says fill the wall with water
