Simple, kids. Now sit on Grampa's lap and I'll tell you how the Jews did the World Trade Tower incident. You see, a while back the Nazi's had concentration camps and put loads of Jews and many more unfortunate folks to die in these wicked, vile camps. When we liberated the Jews and the others from the Nazi power we took some in but most were sent to Israel and they pissed of the Muslims and they flew a couple planes into the trade towers.
Now you can say that to those fags who say "CONGRESS, FBI, BUSH DID 911 LULZ!!?" and you can bitch slap both sides of the heads with that bulletproof comeback.
