Shia LaBeouf's first dalliance in the spotlight was a world away from Hollywood - he started out as a foul-mouthed stand-up comic when he was just 10 years old.
The actor followed in the footsteps of his grandmother and started working the adult comedy circuit before hitting the bigtime on the Disney channel.
But LaBeouf left audiences aghast with his bizarre routine - when he started cracking blue jokes about his parents' sex-life.
He tells Britain's The Guardian newspaper, "My act was like, 'Yeah, I walked in on my mom and dad screwing today... and you go from there, building up such a disgustingly accurate description that the audience would start thinking that it was insane what they were listening to - this little kid they can't yell back at, and who can only legally perform if all the alcoholic drinks are taken off the tables.
"Tough crowd! And telling jokes about things that no 10 year old should even know about."
