In this episode, it's revealed that Cosmo sings Soprano (despite being a guy).
In this episode, Wanda calls the Timmy clone a "twerp", a well known line said by Vicky.
It may be possible that Anti-Fairies are not allowed to participate, despite the fact that it said in Da Rules that 'When a fairy godparent quits the position can be filled by any magical creature, but, since the anti-fairies are not seen during the Fairy Idol episode and another possibility is that since they are the fairies opposite, so they have no need to become a Fairy Godparent.

If Jorgen said there are no duets in "Fairy Idol," why did Cosmo perform alongside Norm? That's called a duet!
In the first few airings, when Jorgen said "I don't want beaver doodie on my stage.", the captions said DUTY in place of DOODIE. It was as if it were beaver work, instead of beaver poop. This was fixed in subsequent airings.
And how can one clean up another one's work? Well, sometimes work can be messy.
