Leaning Tower's Reactions

Alright listen up, dummy! The Leaning Tower of Pisa is leaning, right? This joke implies that the Twin Towers *didn't* lean 'cause they fell right away when they were attacked. So, the Tower of Pisa's still standing because it had better 'reactions,' meaning it didn't collapse immediately. Get it? You probably don't, given your track record of face-planting into walls.
