Lil Wayne was gifted a key to the city of Lafayette in his home state of Louisiana, and Mayor-President Joel Robideaux made sure the key was made into a one-of-a-kind gold chain. Robideaux told the New Orleans rapper, "We want to present to you a very special key to the city that we made specifically for you. One of a kind, nobody else has it. ... That's the only one in America. Thank you, sir."
This came before Wayne took the stage at the University of Louisiana Lafayette, which was the result of a student-led charity contest. The Alpha Pi Alpha Fraternity won the contest after donating after 7,000 bottles of water to Flint, Michigan during the water crisis, earning the school a free concert from Wayne.
