Dirty Jobs (2005)

S02E14 Hoof Cleaner

Mike Rowe starts his adventure at a rock quarry in Washington, where he discovers the process of transforming large rocks into gravel, even taking part in blasting a mountainside. Moving on, he dives into a messy job with the hippo caretakers at the Adventure Aquarium in Camden, NJ, getting thoroughly covered in mud. To wrap up his day, Mike assists a team of hoof trimmers pampering cows with pedicures and takes on the task of cleaning their foot bath.
