Turns out the Terminator can move.
Presented with a roulette wheel of dance moves by hosts Bow Wow and Keshia, the 66-year-old actor and former governor of California at first joked that he was "a machine" and doesn't dance.
But when he landed on the Nae Nae, Schwarzenegger launched into the dance with gusto.
Then, Manganiello, 37, landed on the Stanky Legg.
"What's a stanky legg?" Schwarzenegger asked his hosts. "You mean stinky leg?"
After a quick demonstration by the hosts, Schwarzenegger joined his co-star and shook a leg with a big smile on his face.
