A rapper created by Bob Costas while playing the piano for Jimmy Fallon on the Winter Olympics post-game show. Jimmy was writing his weekly thank you notes and Bob, who was playing the piano, stated that his playing was "A little monotonous." ... He is not to be confused with Lil' Wayne, Lil' Bow Wow, or Lil' Romeo.
Jimmy- Thats some nice playing Bob

Bob- Thank you... Its a little monotonous.

Jimmy- ..... By the way He's gonna be on the show next week... He's a great rapper.

Bob- oh he's gonna be on the show, along with Lil' Wayne?

Jimmy- Yep with Lil' Wayne... Lil' Monotonous
