Beastie Boy Mike D. flexed his 'License to Ill' on 'The Colbert Report' last week in order to settle a crossword puzzle dispute caused by the misuse of a term in a recent edition of 'The New York Times.'

Comedy Central's Stephen Colbert decided to settle an argument between New York Times crossword puzzle editor Will Shortz and blogger Julieanne Smolinski on last Thursday's episode of 'The Colbert Report.' The beef was caused by Shortz' clue for the term 'Illin,' which he described as "Wack, in Hip-Hop." After some back and forth between Smolinski and Shortz, Colbert brought in "the only authority with a license to ill" Beastie Boys' "head grammarian" Mike D. to mediate the dispute.
