As if the past 24 hours haven't been bad enough for Mark Cuban -- now he's getting mocked by former sitcom star Mark Curry, who says he LOVES that Cuban got burned in the DeAndre deal.
"TOO BAD MARK CUBAN," Curry told us ... saying a handshake deal isn't worth squat and that DeAndre had every right to bail on the Mavs because nothing was ever signed in ink.
FYI -- Curry is a huge Golden State Warriors fan ... and during the clip, rips both the Clippers and the Mavs ... calling 'em both LOSERS.
It's kinda funny.
Plus, Mark also goes off on Jason Pierre-Paul ... saying the NFL is "out of control" after 2 players blew up their hands in 4th of July fireworks accidents. Check out the clip.
