That's gotta mess with ya:
A Gandhi-following, peace-loving, free-spirited vegetarian who was adopted at birth has discovered the worst possible thing a son could find out about his father – his dad is Charles Manson.
"It’s like finding out that Adolf Hitler is your father," said Matthew Roberts, a Los Angeles disc jockey.
A curious Roberts, 41, began investigating his poisoned family tree about 12 years ago, when he contacted a social services agency, which located his mother, Terry, in Wisconsin, according to the London Sun.
His reluctant natural mom fed him bits and pieces, like his first and middle name — Lawrence Alexander — withholding his infamous surname until she could summon the courage to tell him the truth.
If I had to guess though, I'd say the guy's biological father is Nathan Lane.
