just imagine...
Harry and Voldy standing in a battlefield,their wands raised....and suddenly there are veelas all around in cute cheerleading skirts and they're cheering harry:
"arry, arry, arry "!!!!!!!
Now Voldy gets distracted by the veelas...and harry (who loves ginny so much that he doesn't get distracted by the veelas) shouts"Avada kedavra" and voldy is gone...dead!!!!
