He may get his mouth washed out with soap for this, but you can't blame this kid for the sense of relief he feels when his cast comes off.

This boy is really happy that his cast is being removed -- so much so that he drops an F-bomb before quickly realizing he committed the linguistic faux pas.

His reaction is only eclipsed by the doctor's. He starts laughing like he's a British gentleman watching a 'Benny Hill' marathon.

We say good for the kid. He's probably been through a lot, so put down the bar of Ivory, Mom, and let him just enjoy his moment. But make sure this doesn't become a habit. This could turn out be a gateway curse word.
