Oct. 16 (UPI) -- What do you do with the Gronkowski brothers, Mark Cuban and Alex Rodriguez in the same room? Play flip cup, of course.
Chris Gronkowski was pitching his company Ice Shaker to the sharks. Rodriguez was serving as a guest judge during the episode. All of the sharks wanted in on Gronkowski's business, which sells bottles that are insulated and are used to mix protein shakes.
Rodriguez and Cuban offered $150,000 to Gronkowski for a 20 percent stake in their company. Gronkowski ended up negotiating Rodriguez and Cuban for a 15 percent stake in the company.
"YOU'VE GOT A DEAL, Gronk brothers!" Rodriguez tweeted Sunday.
During the segment, the Gronkowski brothers demolished the Sharks in a flip cup skirmish, which began with a freshly-suited Rodriguez taking his time with the chug.
Chris Gronkowski, 30, played in the NFL from 2010 through 2012. He has suited up for the Dallas Cowboys, Indianapolis Colts and Denver Broncos. The fullback played collegiately at Arizona.
