Richie Incognito has been embroiled in a bullying scandal for much of the last six months, and was seen taking a bat to his own Ferrari. Galifianakis would likely bring up these two incidents, and Incognito might end up leaving feeling bullied.

Los Angeles Dodgers closer Brian Wilson is one of the most eccentric athletes alive today. You can bet that Wilson's beard would be brought up on Between Two Ferns, and that the two characters would seem equally awkward and funny.

Los Angeles Lakers' Kobe Bryant has sat out all this season, so it is a bit sad Galifianakis hasn't invited him on Between Two Ferns yet. Galifianakis would have plenty of fodder to joke about with Kobe, with previous feuds with Drake, Shaq, being an older player and previous legal troubles all providing material for jokes.

Kane has been known for partying and has previously gotten into trouble for allegedly assaulting a cab driver. Galifianakis would tear him apart on Between the Fern, although the American would take it with grace.

Everybody knows about the trouble that Mathieu got into in college because of the failed drug tests. Now playing with the Arizona Cardinals, Mathieu should be able to take jokes about his college troubles, and Galifianakis would exploit this extensively with additional comments on the Honey Badger nickname.

Dallas Cowboys WR Dez Bryant has previously been in trouble for theft and assault, and also left the field after crying in a game last season. These incidents are now behind Bryant, but they would make for great jokes.

Usain Bolt is one of the most decorated track and field athletes ever, as he has won six gold medals over the last two Summer Olympic Games. Bolt is known for having a good spirit, so Galifianakis could joke about the steroid rumors around Bolt.

Boston Celtics forward Kris Humphries could joke with Galifianakis about his brief marriage to Kim Kardashian, and the public feud with Kanye West that came afterwards.

Few people have been publicly shamed like New York Yankees third baseman Alex Rodriguez, It is ridiculous how many angles Galifianakis could take when making fun of Rodriguez, and the star has time to make an appearance on Between Two Ferns because of his suspension.

The unruly John Daly is the antithesis of what most people think of in golfers. This actually makes him a perfect fit to appear on Between Two Ferns, and Galifianakis would make sure the show was fun for all involved.

Ron Artest is one of the most interesting characters in recent sports history. One may call him this generation's Dennis Rodman, and he would make for a hilarious guest on Between Two Ferns.

LeBron James knows how to handle the public eye, but Galifianakis would get him a little on edge. It would be funny to see Galifianakis going after James about not being the best basketball player ever, being lazy to go to the Miami Heat, etc.

Peyton Manning may be the funniest athlete alive today. Anything that Galifianakis could say to Manning would surely be taken in jest, and the quarterback could throw a funny line or two back.

Mario Balotelli may not be especially well known stateside, but he still would be a perfect fit for Between Two Ferns. The AC Milan and Italy striker previously stated he is smarter than the average person, had been involved in numerous spats, and even wore a shirt that says "Why Always Me?". Galifianakis could find plenty of material to make fun of Balotelli with.

Johnny Manziel would be the perfect person to appear on Between Two Ferns, and he would provide a target not seen on the show since Justin Bieber. He is notorious for partying, there are questions about his NFL readiness and how he really doesn't answer to any authority. Simply put, Galifianakis would have a field day with Manziel on the show.
