Sportscaster Bob Costas may be a great sports broadcaster, but when it comes to personality, he lacks. Recently on MLB Now the well-known sportscaster loosened up a little when he rapped the lyrics to one of Ludacris' songs.

It all started when veteran broadcaster Brian Kenny and 12-year MLB veteran and MLB Network analyst Harold Reynolds asked Costas who is favorite rapper was. In typical Bob Costas fashion the answer stared off rather seriously, but then turned to pure comedy. Watch the famous sports guy rap the lyrics to "Hip Hop Quotables" by Ludacris.

I will admit, after watching this video for like 12 times I now a different view of Bob Costas. I am now certain that everyone does have some sort of "coolness" deep down inside, you just have to explore to find it.
