J.K. Simmons -- who you probably know best as the Farmers Insurance guy -- is earning raves and serious Oscar buzz for his latest performance in Whiplash.

Stopping by The Tonight Show Thursday night, Simmons told a story from his youth, where he and his cousins would sing a tune and see who could hit the lowest note. Naturally, Fallon challenged him on the spot -- and Simmons destroyed him.

Safe to say Terence Fletcher, Simmons' tyrannical Whiplash character, wouldn't be so nice about Fallon's best effort.
