Speaking of grown boys and their toys, Brit singer Ed Sheeran and "The Tonight Show" host Jimmy Fallon rocked the house down and set the internet ablaze with their performance of the smash hit single "Shape of You". He recently released two brand new remixes but the latest one would definitely hit the funny bone.

Ed Sheeran, Jimmy Fallon And 'The Roots' Played Around At 'The Tonight Show' With The Smash Hit 'Shape Of You'

Backed by the house band, The Roots, Ed Sheeran and Jimmy Fallon produced this alternative rendition of the song with the use of classroom toy musical instruments. Instead of the usual band instruments, the group was playing around with musical toys often see in kindergarten - Ed was using a banana shaker instead of his guitar, Jimmy played the güiro, while the rest of the band were playing a rainbow-colored xylophone, kazoo, and a miniature piano. Amazingly, nothing about the performance was amateur. In fact, the group sounded superbly good.

According to Eonline, the original version of the hit single "Shape of You" has topped the Billboard Hot 100 in the U.S. five times as well as the Australian and U.K. singles charts for seven weeks. This has even snagged the top spot on iTunes charts from Katy Perry at which the "Fireworks" singer jokingly chided him saying "Thanks, babes, for keeping me off the No. 1 spot, thanks."

Daily Mail reports that this performance is actually a part of NBC's "The Tonight Show'" "Classroom Instruments" series which piloted in 2012 with Carly Rae Jepsen's "Call Me Maybe." The hit single "Shape of You" is part of Sheeran's upcoming album "Divide" which will be out pretty soon.
