What happened to airing her Polygraph re: Joke Stealing?

I must have read in 3 different places that Amy planned to take a lie detector test for Season 4 (and to air those results unedited) in relation to repeated allegations of stealing jokes from multiple sources.

Did I miss this somewhere - or did they just decide it was better to not rehash the story.

It really does something to someone's (already shaky) credibility when they vow to absolutely prove their innocence so emphatically, only to then...
