New Buccaneers quarterback Ryan Fitzpatrick had a lot of time to burn this offseason before signing with Tampa Bay on Friday. 

After officially becoming a free agent on March 9, Fitzpatrick wasn't a hot commodity, which means his phone wasn't exactly ringing off the hook with NFL teams looking to sign him. 

Since Fitzpatrick didn't really have to worry about football for two and a half months because he didn't have a team to play for, he decided to spend his offseason doing something else.

For one, he did dad things, which was somewhat expected, because he's a dad. 

"I've got a lot of time just to spend with my kids. We've got baseball, lacrosse and gymnastics and everything going on right now. It's been a lot of fun," Fitzpatrick said, as he described his offseason during a recent interview with SportsNet New York.  

Besides doing dad things, Fitzpatrick also decided to get a side job. For most people, a side job might involve driving for Uber, but for Fitzpatrick, that's absolutely not the case. 

"I'm keeping busy, teaching a Rubik's cube class and having a good time," Fitzpatrick said.

WAIT, WHAT DID HE JUST SAY?

Apparently, Fitzpatrick has been spending his offseason teaching people how to solve the world's most impossible puzzle. I get a headache just thinking about trying to solve one, and Fitzpatrick is teaching a class on it. 

By the way, now seems like a good time to point out the fact that Fitzpatrick went to Harvard, and that's mainly because if you write a story about Fitzpatrick, you are basically obligated to mention that fact. It's the first thing they teach you in journalism school. 

Anyway, if you're wondering how Fitzpatrick became obsessed with the Rubik's cube, it appears that he got bored one offseason and just decided to learn how to do it. 

"At first, it was just a challenge for me, I wanted to learn how to do it," Fitzpatrick said during an interview from October 2016. "Usually, every offseason, I pick one or two things I want to do, and the cube, I thought, would be a nice challenge because I could never do it. It slowly became a hobby, and then a little bit of an obsession after having some success and teaching my kids, and then my kids being faster than me, and then me trying to be faster than them. It's been fun for our family."

According to Fitzpatrick, it only takes him about a minute to complete the cube. Although that's impressive, it's still a little bit off the world record of 4.75 seconds.
