What you don't know about The Little Couple - Jen Arnold and Bill Klein

In 2009, TLC introduced us to Dr. Jennifer Arnold and businessman Bill Klein—otherwise known as The Little Couple. Through their reality series, we've watched them get married, grow their family, and overcome some crazy obstacles to get to where they are today. Even though their lives have been an open book for TV audiences, there is still a lot you might not know about them. Get ready to be amazed by these little-known facts about the little couple.

Bill Klein was bullied in college

People can be pretty cruel when it comes to differences in physical appearance, so it's no surprise that Klein has faced bullying because of his dwarfism. As a college student at New York University, Klein dealt with name-calling and threats. In his 2015 book, Life is Short (No Pun Intended), he wrote (via Radar Online): "I was called 'midget,' I was teased, I was ignored, I was threatened, I was chased, I was beaten up." As if that's not scary enough, Klein's memoir reveals that he even had to get police involved when students began throwing things at him. It's a heartbreaking account and a testament to what made him the strong person he is today.

Jen Arnold was once Ben Carson's patient

Yes, that Ben Carson, the former presidential candidate. In the couple's 2016 book, Think Big: Overcoming Obstacles With Optimism, Arnold revealed that Carson operated on her when she was just two years old. According to Radar Online, Carson worked with another doctor, Steven Kopits, at Johns Hopkins Hospital in Baltimore to perform a cervical spine fusion. The surgery went well, and these days, Arnold has nothing but happy memories of the time she spent as Carson's patient.

The couple first met at 10 years old

Arnold doesn't remember her first meeting with Klein (she was recovering from surgery), but he remembers the brief encounter clearly. It took place when they were both hospitalized, and he spotted her during one of his routine strolls through the halls. "She was at the end of the hallway, and I was in room like 302," Klein told Glamour in 2015. "I used to do laps around the hallways, and I was happy as could be. I was cut out of my cast…my parents were 200 miles away, so I couldn't get in trouble by them…so I cruised into her room."

They have a really cute birthday tradition

Marking special occasions can be a little difficult when you're doing it in front of an entire camera crew, but it's important for the show to have those personal moments documented for their fans. So the pair give the cameras what they want, and then they celebrate again, just the two of them. "We try to remind each other that dinners out with the cameras don't really count and that we still need to have a separate celebratory dinner for us, for birthdays and anniversaries," Arnold told The Huffington Post in 2011. "Even though we celebrate on camera, we do something separate as well." How cute is that?

Klein considered suicide

Remember all that bullying Klein went through at NYU? It was so difficult he said it pushed him to think about committing suicide. Although it seems his life has definitely improved since those dark days, he told HuffPost Live that college was the "deepest of depression" he's ever experienced, and now he hopes to use what he learned from that difficult time to help his children, Will and Zoey, should they ever face bullying. "I've had bumps along the road every year to deal with, but that said, I hope I can teach my kids to do better than I did when it comes to dealing with people you can't control," Klein said.

Arnold lives by relationship rules

Arnold told People the most important rule of marriage is making sure to carve out quality time with your spouse. "When you have a busy life, particularly two toddlers that can take up all your attention and energy during the day, so you make sure to have something at night," she said. "It could be a glass of wine after you put the kids to bed, watching a TV show, making sure you give at least 10-15 minutes of your time to each other." And never ever go to bed angry, she said. "We, like everyone else, have arguments, but we don't let it go to the morning. Everything is resolvable, even if someone has to say they're sorry." Has this couple they ever thought about becoming marriage counselors because we think they'd rock it.

Klein was a troublemaker as a kid

In an interview with the blog Dad or Alive, Klein admitted that he got into plenty of trouble as a kid, especially when he was a teenager and wasn't keeping up with his schoolwork. "From silly things to serious things, I'm sure I tested every boundary there was," Klein said. "One of my most serious offenses was in 9th grade. My grades had dipped to…well, unacceptable lows. I disobeyed [my dad's] many requests and finally he was forced to take away everything I valued…television, friends, everything outside of school." Apparently, his pop's punishments worked, because Klein said he was an A student from that day forward. Those valuable lessons should serve him well as he parents his children.
