Everybody dance now!
The latest viral video clip will have you jumping on your toes and doing just that thanks to Christopher Walken and some very skilled editors over at the Huffington Post who pieced together clips of the actor dancing in 57 of his films.
Whether he's breaking it down in 1988's Puss and Boots or busting a move beside John Travolta in 2007's Hairspray, the mashup clip is sure to put a smile on your face as Walken shows off his smooth dance style.
Coincidence that today just happens to be International Happiness Day? We think not.
