Richard Simmons is 76

The guy who got us “Sweatin’ to the Oldies” is 76 today!

Happy birthday to fitness guru Richard Simmons!

He was constantly on our television sets in the 1980s and ’90s, with his fitness tips, late-night talk show appearances, and popular exercise videos.

But on February 15, 2014, he simply didn’t show up for the fitness class he taught in Los Angeles – and hasn’t been photographed in public since.

His abrupt disappearance raised a lot of questions, and even sparked a podcast titled “Missing Richard Simmons.”

There were some outlandish theories, like he was being held captive by his housekeeper!

Other, probably more appropriate theories, is that he became a recluse and simply wanted to be left alone.

Ten years after he disappeared, he’s now posting quite regularly on Facebook and even holding online chats with fans!

He also posted in May that he may be headed to Broadway…

Pauly Shore also recently portrayed Simmons in the short, “The Court Jester.” It’s now on YouTube, below.

Wherever he is, and whatever he’s doing, happy birthday to Richard Simmons!
