Journalist and anchorman Brian Williams signed off for the final time last night after 28 years with NBC. You can see his farewell from last night’s episode of The 11th Hour on MSNBC. We wish him the best in his retirement.

Over the years, Jimmy Fallon’s crew at The Tonight Show has had a lot of fun with Williams’ news footage, editing him word by word into popular rap songs.

These are genius (warning: some explicit lyrics).
