Jesse Teeters and his young daughter might be the newest musical sensation.

Teeters, a photographer from New York City, called the video of his duet of the Sesame Street classic 'Mahna Mahna' with his young daughter, 'My Greatest Achievement.'

He describes it as 'the culmination of 2.5 years of parenting' on YouTube.

Well done, Teeters, this is adorable!
