Back in 'Jersey Shore' House

Apparently the "Jersey Shore" cast enjoys a big pain in the ass, because we've learned Vinny has returned!

As TMZ reported Saturday night, Vinny and the cast went to dinner and a club last night, in an effort to heal the deep psychological wounds between them -- and apparently it worked. Vinny was spotted as he made his way into the house (above) ... carrying a bag of laundry.

We broke the story ... Vinny stormed out of the house a week ago and returned to his home on Staten Island, vowing never to return to the show.

What's interesting ... at the time he left the cast, crew and producers were happy about it -- or at least they said they were -- because he was a pain in the ass.

Maybe it was a story line, maybe it was just fickle silly youth -- Jersey has just regained the glory of Vinny.
