A running gag in this episode is that bad luck happens when Timmy accidentally does something that causes bad luck.
When the time that anti-Fairies made it down to Earth, they cause disaster to all people. But Timmy's parents are not affected by their magic because they are wearing good luck charms .

Innuendo: According to a billboard, one of the mascots in Adrenaland is a pill named Phen Phen Phil. This is a reference to the combination of the drugs fenfluramine and phentermine, a.k.a.

The Anti-Fairies can only be seen with some special Anti-Fairy goggles in this episode, but in later episodes they can be seen without it. Although in The Gland Plan the anti-flight battle suits or the prison itself may have had something to prevent them from being invisible and from When Nerds Collide onward, Jorgen made sure through the Da Rules that they will remain visible if they try to wreck any havoc on Fairy World or Earth.
When the Anti-Fairies are going back to Fairy World at the end, Anti-Cosmo has redneck teeth like Anti-Wanda.
