However, you likely won't notice those vacant spots.

That's because any time a celebrity gets up or a seat isn't being used, professional seat fillers are there to swoop in.

The A.V. Club chatted with one anonymous seat filler who says to even be considered you basically have to know someone who works for the Academy or PricewaterhouseCoopers, the accounting firm that counts the votes.

From there, organizers might even ask for a resume, links to social media pages, pictures of yourself and more.

CNN spoke with one seat filler who laid out the guidelines:

"As a seat filler, there's a lot of rules you have to follow starting from the dress code. No picture taking. Most important, don't talk to the celebrities unless they talk to you," Monica Enriquez said.

Which might just be the toughest part of the gig. MTV writes, "Holding your tongue while Ryan Gosling is sitting right in front of you might be the hardest part of this job, so only the strong-willed need apply."

Now, if you think you've got what it takes to be a seat filler, AOL lists a few sites where you can apply.

Seat fillers aren't typically paid, but maybe sharing a slice of pizza with Ellen Degeneres and bragging about the whole thing would make it totally worth it.
