Unlike 50 Cent and Floyd Mayweather, the Twitter beef going on between Mavs owner Mark Cuban and Donald Trump seems to be the real deal. Initially, the feud started when Cuban responded to Trump, who promised he would donate $5 million to charity if Barack Obama showed his college transcripts and U.S. passport records, by offering $1 million to a charity of The Donald's choosing if he shaved his head

Obviously, Trump, a man who covets his hair, didn't take the deal but instead fired off with a series of tweets directed at the Mavericks owner. 

Not one to back down from a verbal spat, Cuban responded with a tweet that borrowed from a joke Obama made previously in response to Trump's $5 million offer. 

While the Cuban/Trump Twitter war seems far from over, who's winning the battle so far?
