Cops say he was furious when one of his groomsman, Travis Cullen, was dancing "inappropriately" with his new wife Khamla.
So the newlywed who according to a police report "seemed very intoxicated" shoved his pal into a ceramic pillar with such force that he knocked it over.
It fell near guest, Andrew Phipps, who just happened to be an off duty cop, who tried to subdue him.
Police reports say Phipps ducked several punches from Twombly, then grabbed him and fell into a wall when other officers joined the scuffle.
He was then hauled off to the cells to sober up.
Fellow guest John Ellsworth Frederick Schildberg III, 63, was also arrested, but told the Des Moines Register: "The police officer completely lost it."
"I didn't touch the officer at all except on his bicep, and he went berserk on me. He pinned my head down with his knee."
He added the number of officers who attended, estimated to be between 20 and 30, was also unnecessary.
"You don't get that many at a bank robbery," he said.
Twombly was charged with criminal mischief, two counts of assault on an officer, and disorderly conduct.
