If YouTube were a thing in 1972, this definitely would have gone viral! Two astronauts on the Apollo 17 mission get to singing while they are hopping around the Moon, and it's just an amazing thing to watch. My favorite part is when one of the guys comments that he is skipping and the other dude gets SUPER uptight about the implication he's doing the same thing! It's a short and sweet 30 seconds worth your time, check it out below.
Also, who messes up the "month of May" line?!
