Anyone remember when animal planet aired that mock documentary

About the history of mermaids and how they were real bug the governments of the world were covering it up. They even had a fake scientist on it. Everyone without an ounce of sense thought it was real and started raving about how mermaids were real. Then when they discovered the obvious fact it was a mockumentary and not real they got pissed at animal planet and the ceo eventually got fired. Then they promised to not do it again but made a sequel to it.

It was an entertaining fake documentary though.
