Wisconsin's defeat to Kentucky in the Final Four was painful for more than one group of Badger's students after an a cappella group had to pay off a bet.
The group, Fundamentally Sound, from Wisconsin bet with their Kentucky rivals AcoUstiKats over the result of the two college's clash.
As a result Wisconsin had to sing a Kentucky fight song on video. You can check out the whole performance in the video above.
Although the Badgers' rendition of 'on, on, U of K' may not have been the most heartfelt of songs, credit must go to Fundamentally Sound for following through on their wager.
I'm sure that Wisconsin's blue team spirit will not extend when Kentucky face UConn in the National Championship game later today.
