I hope someone gave this guy a good lap dance -- after all the crap he's been through he certainly deserves a little love!

On Saturday night Joaquin Phoenix and several pals hit up Plan B strip club on Pico Blvd in West LA, and after spending several hours inside the club, the actor/failed rapper left smoking a cigarette and covering his face, but he didn't look that bummed.

Our photographer on the scene tells us: "Joaquin wasn't really embarrassed to be seen leaving the club. He looked like he needed to release. He came out so ready for a smoke!" Sounds like he had a good time!
