Jack Nicholson -- OK, I'll Give The Lakers Another Chance ...

One season after he joked about getting rid of his seats, Jack Nicholson returned to Staples Center Wednesday night ... supporting the Lakers at their home opener.

Don't forget, both Nicholson and his famous friend Lou Adler expressed some serious frustrations with the team last year ... and it seemed like the Purple & Gold were in danger of losing their biggest fans.

But last night, there they were ... Lou and Jack back in their regular seats -- hoping this would be the year the Lake Show gets their groove back.

They lost.

Wonder if we'll see 'em again at the next home game on Sunday?
