It was on this day, 40 years ago (8/16/77) that we lost Elvis Presley at the age of 42 to heart failure. If he were still here, he'd be 82. This is how he might look now.

We know a lot about him but not everything. Here are some things you may not know about the King including what he got for his 8th birthday that might have changed history.

You know he loved his mom, Gladys. He bought her Graceland and a pink Cadillac. You may not know that at her funeral in 1958, he tried to jump into her grave. He also carried her nightgown around with him for a few days.

He was a very spiritual man. I think his gospel albums are some of the best ever made. Elvis was known for singing gospel songs for hours after some concerts.

He said that it brought him great comfort and sometimes sang until dawn.  Obviously before "Elvis has left the building."

He made 31 movies over 13 years. He loved his early stuff but hated most of his later films. In "Stay Away, Joe" he sang to a bull.

Elvis's gold suit was real. He had it designed for the opening date of a 10 city tour in 1957. It cost $2,500.

During the show, he fell to his knees and left a pile of gold leaves on the stage. He was told never to do that again.

We know he gyrated on the Ed Sullivan Show. Milton Berle was the one who may have started it all. He was on Milton's show in 1956.

He asked Elvis to perform without his guitar, reportedly saying, "Let 'em see you, son." Elvis' gyrating hips caused outrage across the U.S. and within days he was nicknamed "Elvis the Pelvis."

Okay here's the birthday moment, you've been waiting for.

On his 8th birthday he got 8 dollars and a can of soda pop. It was 'all shook up' and the rest was history. Wow! That totally wasn't worth the wait.
