In Episode 3 of Season 2, "When Aliens Attack," it was revealed that the Leaning Tower of Pisa was in "Monument Beach" in New New York. It was supposedly stolen by New New York's supervillian mayor in the 2600's
When the aliens came, the Tower wasn't blown up like everything else but it just fell over.
The Tower was apparently back in Italy in tonight's episode. Perhaps once monument beach was destroyed the Italians took back the fallen tower and fixed it up.
What do you guys think?
