There are some similarities between Seagal and SMM - delusions of grandeur.
During the early part of his career Seagal tried to pose as a CIA hit man, a mafia insider etc...in other words create a tough guy persona for the public.
All the lies unravelled when his partner Nasso ( who had real mafia connections ) was tried and imprisoned for embezzlement or some similar crap. During the court proceedings Seagal had to come clean about his grandiose stories and admitted that they were made up. He also lied about being the only westerner to run an aikido dojo in Japan and battling the yakuza when in fact it was his father in laws dojo ( his first wife was Japanese) and the only battle he got into in Japan was chasing a drunk out of the dojo. Let's not forget the Gene La Bell incident where the wanna be tough guy was choked out by a genuine tough guy. Seagal apparenty lost control of his bladder when Gene choked him out....twice.
