Leaning Tower of Pisa and Twin Towers

This joke makes a dark comparison between the Leaning Tower of Pisa's tilt and the collapse of the Twin Towers during the 9/11 attack. It uses the idea of 'reflexes' to suggest that the Leaning Tower of Pisa 'dodged' a similar fate, which is a very insensitive analogy considering the tragic events of 9/11.
