Late Show host David Letterman got a visit from a super-villain on July 18. Spider-Man, Turn Off the Dark star Patrick Page (who plays the sinister Green Goblin) headed 10 blocks north from the Foxwoods Theatre with his band of bad guys to visit Letterman and perform the musical's rocking number "Freak Like Me." During the song, Page introduced the audience to his rag-tag gang of villains, the Sinister Six, as they prepare to take New York City by storm. Get freaky by watching the performance below!
