SUED Over Roller Coaster

Drum Stunt

The man who claims he invented Tommy Lee's awesome roller coaster drum solo thing has kept his word -- officially following through on a promise to SUE the drummer ... for allegedly jacking his design.

L.A. based engineer Scott King filed the lawsuit in L.A. County Superior Court, claiming he approached Lee back in 1991 with an initial design for a drum-roller coaster for his concerts ... and Lee jacked it for Motley Crue's 2011 tour.

Now King is suing Lee for stealing his idea -- demanding at least $400,000 in damages.

TMZ broke the story ... King sent Lee a warning shot last month -- in the form of a legal letter -- promising to sue if Lee didn't pay up. Well, Lee didn't pay up.

Lee's attorneys responded to King's letter claiming King's full of crap ... he never pitched Lee Squat.

‘America’s Got Talent’ Star In Stunt Gone-Wrong — Breaks Bones, Poops Pants

'America's Got Talent' Star
In Stunt Gone Wrong --
Breaks Bones, Poops Pants
The nut-smashing "America's Got Talent" star who became famous for abusing his testicles on TV was seriously injured in a stunt-gone-wrong ... suffering several broken bones and a soiled pair of underpants, TMZ has learned.

The man at the center of the painful situation appeared on the show as "The Horse" -- real name Zac Gordon.

Gordon tells us he was filming a stunt last weekend with some of his "AGT" buddies in which he was supposed to jump from a two-story roof and land crotch-first on a wooden plank.

In the video ... you see Horse hit the plank -- but he says he ultimately landed on a bucket of cement that was being used to hold the wood in place.

Horse tells us the impact was so intense ... he broke several ribs and defecated in his shorts upon impact. 

The amateur daredevil says he refused to go to the hospital ... but consulted with a doctor afterward just to be safe.
