Don’t blink, or you’ll miss the silliness.

Robert Downey Jr. goes where Jared Leto went before in an “Intense Staredown” against “Tonight Show” host Jimmy Fallon.

In a segment of the mountaintop zen battle on Wednesday’s show, Downey and Fallon duel empty thought for empty thought, even managing to evoke “The Brady Bunch” and Domino’s Pizza.

Ridiculousness wins. Doesn’t it always?

“The Tonight Show starring Jimmy Fallon” airs weeknights at 11:35 p.m. ET on NBC.
