Dwayne "The Rock" Johnson is making the rounds for the upcoming Hercules movie, and he stopped by Jimmy Fallon for a word and some signature Fallon antics (cheeky giggles included).

The two pretended to be workout gurus from different eras; it was a great excuse to watch The Rock gently exercise. More importantly, it's the perfect excuse to watch The Rock handle a "Jack Weight™" and make some healthy masturbation jokes. For those of you who simply cannot wait, jump to 2:30.
