I'll give you one... This one occurred prior to his ISU tenure.
The refs always meet with the coaches prior to the game inside the locker rooms. Mangino used to think it was funny to strip butt naked in his office prior to the refs walking in so when they did there he was in all his glory.
The guy has some screws loose. The rest of the stories I've heard were mostly examples of his temper.
Can't . . . un-see.
