Plano police are investigating the death of Matt Osborne, better known as Doink the Clown, one of the greatest of all evil-clown WWF characters.

Police say the 55-year-old Osborne "was found in his Plano, TX, apartment on Friday by his girlfriend, who reported that he was unresponsive. He was transported to a local hospital where he was found dead," according to Sportsgrid.com. (We sorta hope he was in costume at the time.)

Although other wrestlers have donned the iconic Doink makeup, Osborne was the original, playing Doink from 1992 to 1996.

Doink appeared in the audience in the early years, according to Pro Wrestling Insider, wearing "a bright green wig, white, red and blue facepaint, and a colorful polka-dotted outfit."

But he quickly became an "evil" clown "who played cruel jokes on fans and fellow wrestlers," according to Sportsgrid.com.

Osborne had recently posted on Facebook that "I HAVE SOO MUCH GOING ON THIS SUMMER dON'T KNOW IF i'M COMING OR GOING! bUT......THAT'S THE WAY HU HUH i LIKE IT HU HUH HU HUH! mISS MY BROTHERS!!!!"

Sadly, the world will miss out on what Doink could have accomplished as an elder-evil-clown statesman. Rest in peace.
