Sports enthusiasts love to trash talk, but at a football game you could go hoarse quickly from all that yelling. What better way to express yourself as a fan than with a homemade sign. The perfect gameday sign can express cocky boasting, political humor and just downright dirty jokes all with a few lines of text and/or a quirky picture.

But doing it right is an art.

The makers of the following signs are true artists. That's not to say they're drawings are good (at all), but they know what it takes to make that attention-grabbing, memorable, no-they-didn't fan sign. And for that, we salute them.

It's vulgar, but effective.

Everyone loves a Chuck Norris homage.

 See, more Chuck Norris.

 This one's in here mostly for the artistic skill.

 Nice pop culture reference. 

Haha, fat chicks.

Giant underwear is always a good idea.
