When Jerry Jones was caught talking on a flip phone last month, it caused a stir on Twitter.

Why, everyone wanted to know, was a man with a net worth of nearly $3 billion, using an outdated phone?

In an interview with CBS Good Morning, Jones faced his critics. He confirmed to Jan Crawford that he does indeed still use a flip phone. Sure, he may have a fortune, but he didn't get to this point by spending lavishly.

"It's how you have a stadium worth $1.2 (billion)," Jones said of his frugality. "If you watch your pennies and you have flip phones. You can't have it all."

While that makes sense to a certain degree, Jones' stubbornness is actually rooted in practicality.

The flip phone, Jones says, is both more comfortable and safer.

"It's free of hip dialing," Jones said. "You can have some pretty confidential conversations and not get overheard by the camera man by talking into this flip phone."

Here's the entire interview, with Jones discussing the flip phone at the :43 mark.
