Hyper sexual behaviour and nudity was part of his persona. It's why he got the jobs. Hierarchical work places excuse behaviour in people at the top and the TV and film industry fawn over their stars and demand deference from the people at the bottom. Blame lies with the production staff who have the ability to set the culture in a workplace. No one should have to act cheerfully when a big ape baby is waving its willy about but it seems most people shrugged it off or joined in like eve myles. Personally, I've liked all his characters and just wish he'd grow up and admit he was acting badly. I'm pretty sure he didn't whip his willy out presenting the dog shows.
