Artie Lange, sidekick on the Howard Stern Show, has checked into intensive outpatient rehab for substance abuse.

Lange, 40, has struggled with narcotic addiction for years and has been to rehab many times before.

It seems he’s back to his old ways.

Last April he walked off the air after having an physical altercation with an assistant and it was thought he may have been using again.

Artie has been very open about his drug use, telling listeners story after story about being drunk to snorting cocaine and heroin.

I hope the guy gets clean, because yeah, he’s funny. But he’s also a fat f***ing loser. His mom still cleans his apartment and brings him food..

He’s just lucky enough to have Howard there to deal with his shit, because not many other employers would put up with him. He’ll eventually end up a nobody, a washed up old comic. Then maybe he’ll realize how good he had it.
