Will Ferrell and Red Hot Chili Peppers drummer Chad Smith have long found themselves near the top of every celebrity-lookalike listicle, and last week, we learned the news that the two would stage a drum-off for charity on The Tonight Show. That drum-off happened last night, and massive credit is due to Will Ferrell for stretching a thin “these guys look like each other” comedic conceit into some deeply entertaining television. Ferrell and Smith came out together, dressed exactly alike and pretending to be one another. And in the actual drum-off, Ferrell, at the very least, proved capable of pretending to hold a beat. The whole thing built to an absurd but inevitable conclusion, one familiar to everyone who’s ever watched the “more cowbell” SNL sketch (which is everyone, ever). Watch the drum-off below.

RHCP stuck around to perform Funkadelic’s “Standing On The Verge Of Getting It On” and Blood Sugar Sex Magik favorite “Give It Away” with the Roots as well.

Unexpected takeaway from this thing: Will Ferrell and Chad Smith actually don’t look that much like each other.
