Snoop Dogg Ice Cube Ain't Got NOTHIN' on Me ... As an Actor!!!

EXCLUSIVE

Many rappers have dipped their toes into the acting world ... Ice Cube, Ice T, LL Cool J ... but Snoop Dogg tells TMZ he's the GREATEST rapping thespian of ALL TIME!!!!

He might be right ... Snoop's been in a TON of stuff -- including, "Half Baked," "Training Day," "Bones" ... plus, he voiced Dangle the STD-infected puppet on "Chappelle Show" and got streaked by Will Ferrell in "Old School."

Sure, Ice Cube may have starred in a bunch of hit movies ... and T and LL got themselves starring roles on major long-running TV action dramas ... but Snoop kept his composure while standing next to an ass-naked Will Ferrell.

That's impressive.
