Mark Cuban is one of the most outspoken owners in sports and real estate blowhard Donald Trump is one of the most outspoken businessmen in America, which is one reason why the two got into a Twitter battle after the NBA owner appeared on "The Tonight Show".
According to Yahoo Sports, the two have been going at it for a while this past year, as Cuban offered Trump $1 million to shave his head as a joke response to his asking of President Obama to show his college transcripts for $5 million, which Trump said he would donate to an AIDS charity or the inner city because that's all he could think Obama would care about.
Cuban took things further on Wednesday on the "Tonight Show" when he was a guest with Jay Leno and pulled out a letter he received from Trump back when his reality show "The Benefactor" was cancelled.
According to Yahoo, Trump wrote: "When I initially called you to congratulate you on The Benefactor - little did you or I realize how disastrous and embarrassing it would turn out to be for you. If you ever decide to do another show, please call me and I will be happy to lend a helping hand."
"Can I just say, Donald, how's that working out for you now?" Cuban told Jay Leno's audience, referring to the tough ratings of "The Apprentice", which have been hurt by Trump's baseless attacks on Obama.
Following the airing, Trump wrote on Twitter: "I watched Mark Cuban on Jay Leno last night - what a jerk!"
Yahoo writes that Trump has mentioned Cuban in nearly 20 tweets over the past week, including he is "short off the tee," a "weak man with a big mouth" and has "no clubhead speed" - his personality - "@mcuban has less TV persona than any other person I can think of. He's an arrogant, crude, dope who met some very stupid people" - and his Dallas Mavericks - "why does @mcuban continue to embarrass the 31-35 & 11th place @dallasmavs with childish behavior."
Cuban then wrote: "You just see this crazy life I have & you're in awe.I'm just gonna take over the world while you getting mad" and later said "@realDonaldTrump let's settle this like gentleman.I challenge u to a Harlem Shake duel.@SharkTank cast vs Apprentice cast.For charity."
Cuban later couldn't help himself, adding: "@realDonaldTrump on that Harlem Shake offer, we can all bring our birth certificates if that helps..."
