Manly Dads Belt Little Mermaid Song [VIDEO]

Becoming a parent changes everything -- this group of manly men singing mermaid Ariel's famous ballad is all the proof you need.

Cops, firefighters, construction workers, barbers and Marines belt out every word to "Part of Your World" from the Disney classic The Little Mermaid -- all at their daughters' request. Produced by Tom Riles and Patrick Quinn, the video was originally posted on Life of Dad, a social networking site for fathers.
