Ed Reed is undoubtedly one of the greatest players to ever step foot on an NFL field. He's a future Hall of Famer and is widely considered to be one of the best safeties of all time.

Despite those facts, he's still treated like a rookie up in Buffalo, where he's an assistant defensive backs coach with the Bills. He got the rookie treatment from the team this week, with a slight testament to his title of being the G.O.A.T., or the greatest of all time.

Prank this morning in my office! But they didn't know we were buddies from awhile back #Bills pic.twitter.com/MlxWo1vHHY

Yep, he found actual real-life goats in his office, which is both hilarious and fantastic. Goats are the best, especially when under the desk of arguably the No. 1 free safety in NFL history.

A couple of Bills players seemed to enjoy the prank.

In his career, Reed was named Defensive Player of the Year, was a five-time All-Pro and was named to nine Pro Bowls. Translation: G.O.A.T.
