Mark Jumps Back in to 'Mess With Daniel' - Shark Tank

After going out earlier in the bidding for Foam Party Hats, Mark Cuban is enticed back into the fray by Lori Greiner. Daniel Lubetzky has made an offer to entrepreneurs Manuel and Grace Rojas, but it's contingent on Manuel quitting his job and focusing on the company full time -- which Mark thinks is a bad idea. So Lori joins forces with Mark to make a dual offer. From season 12, episode 5 of 'Shark Tank.' Watch 'Shark Tank' FRIDAY 8|7c on ABC, streaming, on demand, and Hulu.
