It’s hard to believe, but teenagers these days don’t remember a time when touchscreen cellphones were not around. Now, a viral video is showing this in a hilarious way!

The video shows two 17 year-old boys given the challenge of dialing a phone number on a rotary phone in five minutes. The two boys are hilariously baffled by the phone, as they have no idea what to do with it!

The pair start by trying to push buttons on the phone, but they have no success with that. It takes them about a minute to realize that they are supposed to rotate the dial using their finger and dial it all the way around to register an individual digit. Nearly one and a half minutes in, an adult informs the boys that while they have successfully dialed the number zero, they have failed with every other number.

The boys then pick up the receiver for a second, but they quickly put it down.

“You guys have made it all worth it. Everyone has struggled like you have,” the adult tells them.

More than two-and-a-half minutes into the video, one of the boys asks, “Wait a minute, are we supposed to pick up the phone and then do it?”

With 35 seconds left, “What’s with all the holes, though?”

“That’s such a great question,” the adult replied.

Just when it seems like the boys may finally figure it out, they run out of time! The video was posted to social media by Kevin Bumstead, who explained that the boys were his two nephews.

“I saw a video similar on YouTube and I thought it would be funny to see how my kids and their cousins handled this challenge at Christmas,” he wrote. “So I divided them up by age group (24, 22, 22) (19 & 19) these 2 (17 & 17) and (14 and 12) and gave them the phone number and 4 min to dial the phone. These two were the most entertaining and they took the longest and sort of figured it out.”
