Swiss electronica band, Yello — whose biggest hit, "Oh yeah," was made famous in the final scene of Ferris Bueller's Day Off— are objecting to what sounds like a sample of the track in an anti-Obama ad this week.

The commercial, titled "Cool," was released by Karl Rove's Super PAC American Crossroads, and mocks President Obama for being an ineffectual "celebrity." Throughout the ad, a deep-voiced "Oh yeah," similar to the one in Yello's song, is repeated three times.

Here's the ad:

I think it's hilarious that Republicans are always going on about protecting intellectual property when they shamelessly steal music for their campaigns all the time. And it's remarkable to me that Rove's super PAC thinks that young voters will be swayed by 2008's old celebrity accusation. I just don't think that's going to work.
