"Osprey, I await. Pray upon my loins," Downey Jr.'s thoughts are heard. "Mount my torso like the bull of Poseidon."
He continues to ponder, "Earth, air, water fire, Dominos stuffed-crust pepperoni pizza. Nom nom nom nom nom nom nom."
The 49-year-old actor's interview with Fallon was equally amusing. Downey Jr. is expecting his second child with wife Susan Downey and mused that he has some career aspirations for his baby girl. "Our daughter will probably be an actress," the Iron Man actor joked. "That's a stable career."
