her, causing him to decide to run off to California. After meeting up with Donna, who had recently been humiliated by her then boyfriend and Kelso's brother, Casey, they both take off. When Kelso returns at the beginning of Season 5, he finds out that Jackie has moved on to Hyde, which makes him extremely jealous and he spends the majority of the season trying to get her back. Eventually, Kelso claims to be over Jackie and renews his friendship with Hyde, and begins a relationship with Annette (Jessica Simpson), a girl he had a short relationship with in California. Jackie, in the same manner as Kelso had, becomes jealous and even goes so far as to yell, "Get off my boyfriend!" when she sees Kelso and Annette kissing. Kelso responded positively to this and began to make a big show of it. Annette leaves him at the school dance, telling him he isn't over Jackie, and Kelso soon realizes that Annette is right. So when Jackie breaks up with Hyde, Kelso does all he can to win her over, even competing with Hyde at some point. However, when Jackie chooses Hyde over him, he respects her decision and even helps to bring the two together again. From then on, Kelso and Jackie share a relationship as friends. In Season 6, Kelso is the focus of a major plot twist in which he accidentally impregnates a girl named Brooke in a bathroom at a Molly Hatchet concert. Brooke initially does not want Kelso in the baby's life, much to Kelso's relief. However, a pep-talk from Donna causes him to change his mind as he attempts to prove to Brooke he can be a father. In the seventh season, Betsy Kelso, is born. Brooke leaves for Chicago, giving Kelso permission to see Betsy whenever he can. Kelso becomes a policeman, albeit a bumbling one. He attempts to take his job seriously by growing a mustache and calling himself "Mike," and even going as far as flushing Hyde's marijuana stash down the toilet (in The Circle), but he quickly reverts when Hyde and Fez shave his mustache and made the mustache resemble the mustache Adolf Hitler was famous for. He eventually sets the police academy on fire using a flare gun, but even before then, had broken into the academy and gets his supervisor's squad car stolen by Hyde & Fez. At
