Even though this episode took place on Friday the 13th, it aired on Friday the 26th.
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.
Apparently the Anti-Fairies had waited for a long time for a godchild dumb enough to wish them all out of Anti-Fairy World since they remain imprisoned until Friday the 13th when they sneak out of Fairy World to do some bad luck to people.
It is revealed on the 7-7-07 marathon that the President is played by Butch Hartman.
Penn & Teller - The light pole on the corner where Timmy appear have two signs that says "Penn" and "Teller" making a reference to the famous magicians duo.
A running gag in this episode is that bad luck happens when Timmy accidentally does something that causes bad luck.
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.
