The Roots caused some controversy this week with their unique intro song for Republican presidential contender Michele Bachmann when she appeared on 'Late Night with Jimmy Fallon' early Tuesday (Nov. 23).

As Bachmann was greeted by Fallon, the Roots played a riff of a 1985 Fishbone song called 'Lyin A--- B---h.' The ska-tinged song begins with the sing-along refrain of "la la la la la la la la la." Bachmann didn't realize what the Philadelphia band was playing as she sat down and waved to the audience, but fans caught on to the song gaffe.

During an interview on Fox News Channel, Bachmann said that NBC showed sexism and bias to her and demanded that the network apologize and discipline the Roots. Fallon did go on his Twitter page Tuesday evening and apologize for the walk-on song. "I'm so sorry about the intro mess," he tweeted. "I really hope she comes back."

For his part, Roots drummer Questlove also said he was sorry for the song choice. "The show was not aware of it and I feel bad if her feelings were hurt," he told Billboard. "That was not my intention."

NBC has yet to comment on the incident or Bachmann's request to disciplined the Roots.

So what do you think? Should NBC discipline the Roots for their choice of intro song? Tell us in the comments below.
