From what i understand he also used to conduct mettings while on the toilet when he was President. There was also a story about him having the White House bathrooms remodeled to include extra shower heads aimed strategically at his butthole! Weird guy!
LBJ was legendary for that.
He used to sit on the commode with the bathroom door wide open, his aides standing in the doorway as he gave instructions.
LBJ was, if nothing else, blatant.
