The Ghostbusters Easter Egg Only Eagle-Eyed Fans Spotted In 2012's TMNT

"Dinosaur Seen in Sewers!" is the 24th episode of "Teenage Mutant Ninja Turtles" Season 3 and sees the titular team visit the inside of New York's Statue of Liberty. As seen above and spotted by Redditor stegogo, there's a carving on the wall that reads "Venkman was here" — an obvious reference to Bill Murray's "Ghostbusters" character, Peter Venkman. This Easter egg is a nod to "Ghostbuster 2" specifically, which sees the ghost hunters commandeer the Statue of Liberty to defeat the evil Vigo the Carpathian (Wilhelm von Homburg) and save New York City from certain destruction.

While this is just a fun nod to one of the most recognizable film franchises out there, there's another layer to it. As it turns out, the worlds of "Ghostbusters" and "Teenage Mutant Ninja Turtles" are more closely intertwined than most would believe, thanks to an IDW Publishing limited story. The four-issue run from 2014 follows the turtles after one of their new inventions goes haywire, and they end up in the "Ghostbusters" universe. Despite some initial tension between them, the two teams have to learn to work together if they have any hope of defeating the dangerous forces standing in their way.

The Teenage Mutant Ninja Turtles and the Ghostbusters are both pop culture icons in their own ways, and it's pure fun seeing them cross paths in ways big and small.
