Full House: 10 Moments That Show Michelle Tanner Was A Terrible Person

4. Michelle Steals and Marries Her Sister's Boyfriend

Season 6, "The Heartbreak Kid" One Valentine's Day, D.J.'s boyfriend, Steve, tried to be a decent human being and gave a Valentine's gift in the form of a cookie to his girlfriend's baby sister, Michelle. Michelle took this as an act of true love, and proposed to Steve. Again, this was her sister's long-time boyfriend. Michelle knew that he and D.J. were a couple, and she didn't care; right in front of her sister, Michelle proposed. Steve, with the encouragement of D.J. and Kimmie who thought this was all adorable, accepted, and the pretend wedding was on. Except Michelle didn't know it was pretend. She sought out advice from her father, from her aunt, and from her friends, and organized what she thought was a real wedding to steal the man her sister loved. The vows were recited, the rings were exchanged, and in Michelle's mind she was now the new Mrs. Steve... whatever his last name was. Michelle was as convinced as she could be that they were now married, and when her family tried to convince her otherwise Michelle threw her bouquet at the wall and ran to her room. She only agreed to come out when D.J. promised to take her out for pizza. Wait: was this entire mind-freak just to get her sister to buy her pizza? Michelle was not just a terrible person: she may have been an evil mastermind.
