Over 130,000 of these huge oversized bags are being giving out to fans at Comic-Con

When you head to San Diego Comic-Con you're most likely to see fans dressed up in cosplay, people waiting in lines to get into some of the most anticipated panels of the weekend, and giant oversized bags sporting the faces and logos of some big TV shows.

You literally cannot turn your head without seeing a person wearing them.

A look at everyone's shoulder straps will tell you quickly if fans are wearing a Warner Bros.' show bag. The WB logos on the shoulder straps are big giveaways.

The bags are given out to everyone to store their Comic-Con swag as they pick up badges to gain access to the convention floor.

This year Warner Bros. TV is giving out over 130,000 bags to Comic-Con attendees throughout the weekend.

Each bag has one of over a dozen designs from different WB TV series ranging from "Arrow" and "The Flash," to the new "Supergirl" series.

Here's the thing though.

You don't get to pick the bag you get.

You're given one at random. And when you get it, it's folded up into a small rectangle so that you have to unfold it a few times to see what design awaits you.

Obviously, some designs are cooler than others. (Come on, you know you rather have an Arrow or Gotham bag over a Supernatural one -especially if you're a guy.)

The entire experience is like waiting to see what toy is at the bottom of your Cracker Jack box. It could be awesome ... or it could be a temporary tattoo sticker.

It's more than likely you're not going to get the bag your heart desires.

We were pleasantly surprised when we saw that our bag design wasn't among the ones previously announced by Warner Bros.' TV.

It's a "Batman v Superman" one that we quickly heard people were wanting to trade others for. (We were fast to book out of there.)

It's definitely going to be the most sought-after one at the Con, especially with news expected on the film Saturday during Warner Bros. big Hall H panel.
