Rapper Lil Boosie was released last week after five years in a Louisiana prison and he said he found some of the technological advances since then a little shocking.
He told TMZ that even though he had heard of Instagram, he never used it.
Most shocking of all, though, was a little thing called FaceTime.
"I was surprised when I looked on my iPhone," he said. "You can look at people and talk on the phone. ... The world has changed."
