"Cuban became a billionaire out of pure dumb luck. He is an idiot!!"
Donald Trump agrees with you - he's sophomoric and intent to stay that way.
I wouldn't be surprised if the reason Cuban's helping Rosie is to get back to Trump. I saw The Donald ripping Cuban up one side and down the other on a TV interview about a month ago.
My esteem for Trump just went up a notch. Cuban is a cheap roadside punk who got a stupid CEO to pay him 10 times what his company was worth. Dotcom boom "Stupid" money!
