People Editorial Guidelines Published on September 23, 2015 03:15 PM Share Tweet Pin Email Ashton Kutcher came with teeth bared for his guest appearance on Shark Tank‘s season premiere. The actor goes toe-to-toe with Canadian businessman Kevin O’Leary in an exclusive sneak peek at Friday’s opener. “Here’s the thing, you’re belittling people, and that’s not okay,” Kutcher angrily tells O’Leary in front of the other sharks and the presenting entrepreneur. O’Leary tries to verbally fight back, but Kutcher will barely let the star get a word in. “She gave you an answer, and if her answer is not suitable, that’s fine,” Kutcher yells, “but you don’t have to belittle people. It’s not cool.” O’Leary has to have the last word, however, and reminds Kutcher that no matter how much he argues, he still won’t end up funding the woman’s product. “You’re not gonna write a check though,” O’Leary tells Kutcher while the actor tries to argue that the invention “could be big.” Although best known for his Hollywood career, Kutcher has invested in a bevy of successful start-ups, including Spotify, Uber and Airbnb, via his venture capital firm A-Grade Investments. With those names in his portfolio and that fierce attitude, it’s clear Kutcher knows how to make a splash in the business world. RELATED VIDEO: Check Out Ashton Kutcher’s Changing Looks!
