Earlier in the episode he was confessing stuff to Jackie, one of the things which was that one time they were about to fool around and he said that he had washed his hands but he had just finished playing with six dogs. " he is excited that the Petersons have just gotten a new dog, and encourages the gang to go with him to check it out.
Michael has a long time realtionship with Jackie, played by Mila Kunis, a popular and self-centered cheerleader (coincidentally Ashton Kutcher and Mila Kunis are married in real life).
The two lost their virginity to each other after Michael and his friends got out of jail for riding in a car that was mistaken for being stolen.Jackie gets on Michael's friends nerves on a daily basis and Michael repeatedly said that he was going to break up with her.Michael has surprised many by scoring higher on a test than some of his other friends, leading some to believe that perhaps Michael is not dumb, but just naive.Michael failed the first grade for his "refusal" to write in cursive and accidental murder of the class bunny. Michael is one of 7 siblings, including his older brother, Casey, at least two other brothers and a sister (whom Hyde says is an uggo; a term used by Hyde to describe someone who he does not deem attractive, which is somewhat ironic as Michael is constantly referred to as handsome, along with his brother Casey).
But Jackie beat him to it and broke up with him after a pregnancy scare. Michael loves a good burn as much as the next guy, even when the burn is at his expense, but generally he does not mean to severely hurt someone, which he often does but most of the time he hurts people by means of accident rather than on purpose.It is revealed on That70s that the astrological sign of both Michael and Jackie is Virgo.
