It's long been debated among the music and film community whether Will Ferrell and Red Hot Chili Peppers drummer Chad Smith actually both exist or are more likely one man posing as both. Well, the look a like pair are set to get together soon if Ferrell accepts a challenge put forth by Smith over Instagram for both men to have a drum battle.

In the video that Smith uploaded this week he accuses Ferrell or impersonating him and declared ''Drum battle. Me and you. I've seen your skills. You don't got 'em. Let's go.''

The issued challenge comes after Ferrell's appearance on Reddit's Ask Me Anything appearance earlier in the week, in which he addressed the uncanny similarity, writing: "A lot of people think that it's me playing for the Red Hot Chili Peppers. But that would be an insult to Chad Smith. The truth of the matter is there is no Will Ferrell. Only Chad Smith", later adding "It was great to finally clear up the fact that I am Chad Smith."

If you're ask me, a drum challenge is slightly unfair method of determining the greatest of these two identical specimens, being highly advantageous to Smith. Surely there should be some sort of Three Stages Of Hell set up here or something similar, in which the second round involves Smith doing stand up followed by a Steel Cage match for the finale.

Meanwhile, aside from declaring war on his twin nemesis Smith is raising funds for charity, specifically the Make A Wish Foundation, by auctioning his Supebowl drum kit. Nice sentiment, but let's be honest, the guy didn't even really play it

When it comes time to pick sides in this particular duel, we've got Ferrell's back. He's kind of a big deal.
