"I was looking online, and I saw the mattress surfing thing, and it's like, â€˜Hey, man, I've got an old mattress,'" says 16-year-old Garrett. "The most dangerous thing about mattress surfing is the high speed."
Connor, 15, says that they've posted their videos of mattress surfing online. He explains how it works. "It takes two seconds to put the towrope onto the hitch. You just lie down and hold on, and then you just go wherever you can," he says. "One time, our goal speed was to get up to 60 miles an hour."
"It's just exciting," Grayson, 17, says, "going fast and doing something nobody else does."
"When I'm behind the wheel, I want to make it really fun, but I don't really want to run someone over, so that's why I won't pull anybody if they're not wearing a helmet," Garrett says.
"I'm the daredevil of the group," Cody says. "[It's an] adrenalin rush, especially when they whip you around."
Connor agrees. "I'm just holding on, and my stomach is up in my throat, and it's really high-paced."
"We could be doing drugs and driving drunk. Instead, we're just having a fun time," Cody says.
"I recommend Dr. Phil tries it," Garrett says. "If he wants to fly out here and try it, I'll give him a good ride."
Dr. Phil tells the four young daredevils, "First off, let me just be very clear about two things: One, I ain't going to try it." He tells his audience, "Two, these are good kids." He asks the teens, "So, what leads you to tying yourself on the back of a truck to get dragged down the road?"
Garrett says, "Cody and I were driving around one day after school, didn't have anything to do, and I was like, 'Hey, my parents just exchanged out their bed. We've got some mattresses,' so we went into the garage and sneaked the mattress out because I didn't want to tell my parents before I did it, before they shut it down, so I was going to tell them afterward. So we went out and did it, and then we called up the other two and were like, â€˜Dude, this is awesome.'"
"Cody, they conned you into doing something, right? They set up a jump and said, â€˜Oh yeah, we've all done it'?" Dr. Phil asks.
"Yeah. They said Garrett did it," Cody says. "I went pretty high, and then I landed on my head."
What do the boys' parents think of their new sport? The answer may surprise you.
"I would," he says.
"Are you at all concerned that they could go flying and get a neck injury, a head injury, a shoulder injury, break a leg, knee or arm?" Dr. Phil asks.
"I am a little, but they basically do calculated risks. They check the field out. They generally have a spotter. It's a fairly safe risk, in my mind," Chris says.
"This is essentially like driving down the street at 45, 55 miles per hour, opening the door and getting out," Dr. Phil argues.
"They do wear helmets," Garrett's mother, Nicole, says. "They are fairly careful. And the field, Dr. Phil, is completely bare of anything. It's a hay field. There are no roads involved. There is no drinking involved."
"Well, I've got to say there are two things you've pointed out," Dr. Phil says. "They do wear helmets, and that's a good thing, and they are in a field that's pretty flat and has actually got some cushion to it, whereas a lot of people we're seeing on YouTube are doing this down the street with cars on both sides of the street and street signs."
Garrett tells Dr. Phil, "I personally have done that same crash. It doesn't hurt as bad as it looks."
Dr. Phil smiles knowingly for a second or two. He introduces Dr. Travis Stork, an emergency room physician.
Dr. Stork acknowledges that the boys do wear helmets, but says, "It's a terrible idea! Did you see that dummy? When it dove over that mattress and the head hit " what you're not protecting is your spine. You're not protecting your chest. You're not protecting your belly. So, if you were to fracture your spine, when that mattress goes over a hump, you're going to lie there in that field, and you will have lost feeling in your arms, your legs in an instant. If you spent a week with me in the trauma unit, and you saw what could happen to a young man when they actually have an injury from something like this, it won't seem as fun as it seems right now, I promise you."
