Friends alerted me to the sad state of Kermit the Frog since the death of Jim Henson and the loss of Miss Piggy. To see how far he's fallen, view the video of his cover of the NiN song, "Hurt," here. (Warning: the video contains drug use and masturbation by puppet-frogs, as well as acts between puppet-frogs and puppet-bears that would, in at least 36 states, result in prison sentences of up to 8 years.)
Here's a download of Kermit singing "Hurt":Download Kermit_Hurt.mp3
