Everyone has their own definition of normal, thus everyone must also have their own definition of goofy.
However, in the NFL the actions of the majority of the players defines what normalcy is in the league.
The players who don't follow unwritten rules while acting ridiculous and celebrating foolishly, but with great pride, deserve to be labeled goofy.
They are simply entertaining. Whether it be with their looks or their actions, they are known as the goofiest players in NFL history.
Johnson's nickname originated in highschool when he dyed his shoes white as part of a dare, but that is not his claim to fame, or goofiness.
His famous touchdown celebration, the Funky Chicken, is what really proves his status as an NFL goof.
It's a dance based on a song by Rufus Thomas, and it's even more funky on the football field.
These two wide receivers may not be the goofiest to ever play the game, but they deserve some recognition for their famous escapades.
Joe Horn has got to be one of the most daring players in NFL history for his highly original touchdown celebration.
Of course he was fined and penalized for pulling out his cell phone from underneath the goal post padding and calling his children to tell them he scored, but the hilarious celebration was well worth the price and will never be forgotten.
Johnnie Morton's outrageous celebration dance, commonly known as "the Worm," will probably never be seen on an NFL field again. He flopped around right underneath the referee with his arms up signaling a touchdown. I'll leave it up to you to decide if it's priceless or just foolishness.
Unlike Horn, Morton got away with his antics as excessive celebrations were legal at the time. He retired from the NFL in 2005 to take on MMA where he literally got knocked out.
If you're seeking the origin of the famous dance, the "Ickey Shuffle," you have to go back to the NFL career of Ickey Woods.
Woods played with the Bengals from 1988-91 and popularized the celebration which involved the fullback shuffling his feet and spiking the ball as a finale.
Needless to say, the process was quite goofy for such a large man. However, it is now considered one of the most famous celebration in NFL history and possibly the goofiest.
If his outrageous beard isn't goofy enough for you, the Troy Polamalu wig pretty much obliterates any doubts about Brett Keisel's goofiness.
In this particular press conference at the Super Bowl's media day, Keisel made a humorous attempt at spelling the last name of the Steelers' star safety.
Although he doesn't have the best voice, he was also caught singing loud and proud at a Steelers' pep rally.
Keisel grew out "The Beard," which has its own Facebook and Twitter page, because he believes there is a lack of characters in the NFL.
While Keisel described his beard as beautiful and the best ever, he shaved it off at a charity event called "Shear the Beard" in February. The event raised over $30,000 for a local children's hospital.
So at least his goofiness is for a good cause.
Perhaps Portis' most entertaining moments were off the field.
Clinton's crazy alter egos leave no doubt about the running back's inner goofiness.
Looking at the picture explains a lot, but the gold teeth and mohawk just scrape the surface of Chad Whatever-He's-Going-By-Now's goofiness.
He's the NFL's king of publicity stunts, such as the infamous name change and most recently his try out with Sporting KC, an MLS club.
Whether you love him or hate him, the guy sure knows how to celebrate. Chad's flamboyant celebrations include Irish jigs, putting with a pylon, donning a sombrero and poncho, and even proposing to a cheerleader.
Everybody loves Michael, but the gap is goofy no matter how you look at it.
Beyond his happy toothless smile, Strahan is a frequent commercial star and NFL analyst.
He also was a star in the sitcom Brothers, a comedy that he also produced.
The Dirty Bird led by Jamal Anderson is a comical sequence of celebration in which the previously mentioned player leads his teammates in flapping their arms like wings and prancing around like birds.
Anderson is goofy for starting the phenomenom which also became popular with the public and for spreading his goofiness to his friends
T.O. is a fashion model, rapper, actor, author, football star, and to sum it all up, the goofiest player in the history of the NFL.
Owens is so unpredictable. One day he's writing a children's book on how to share and crying for his quarterback, and the next he's having a spat with management and arguing with the guy throwing him the pigskin.
It's no surprise he's even got his own brand of cereal and reality show.
His uncountable celebrations are the best ever witnessed. T.O. is a fan of props such as snowballs, pom poms, sharpies, the Dallas star, and the football as a pillow.
Most of the rules against excessive celebration were brought on by Owens, especially after he began pumping out push ups and sit ups in the endzone.
