<Li> Officer Phillip Otis Kennedy II (played by James Avery) is Kelso's training officer when he joins the police force . He appears mostly in the 6th season, playing a straight ace to the bumbling Kelso . </Li> <Li> Pam Burkhart (played by Eve Plumb in Season 1 and Brooke Shields in Season 6) is the mother of Jackie Burkhart who was dating Bob Pinciotti in season 6 . Once a serious business lady, she fled to Mexico when Jackie's councilman father was arrested for bribery and embezzling $60,000 . She returned to try to fix her relationship between her and Jackie . </Li> <Li> Pam Macy (played by Jennifer Lyons) is a classmate of the main characters of the show . She has been mentioned in more episodes than she appeared . She appeared in the episodes "Prom Night", "Romantic Weekend", and "It's a Wonderful life". In "Prom Night", Michael Kelso took Pam to the prom while temporarily broken up with Jackie . In "Romantic Weekend", Kelso was about to have sex with Pam but was unable to perform, telling his friends "The buffer wouldn't buff". Pam told this to the whole school, which caused everyone to tease Kelso about it . </Li> <Li> Pastor Dave (played by Kevin McDonald), Pastor Dave is the local pastor at the church . He is overly cheerful and (incorrectly) thinks he is up to date with the trends, and is "hip and cool". He is often greeted by Eric and his friends with deadpan voices, and they typically just agree with Dave in the hopes he'll go away . Dave is good friends with Kitty, who helps with the church fundraisers, and has an uneasy friendship with Red (mostly because Red is not used to having friends). His friendship with Red seems to have brought out a less - pure side of Dave, as he spends a day with Red watching football and drinking beer, and once even quit the church because he wanted to watch more football on Sundays (he later rejoins as the pastor again). He appears primarily in Season 3 and 4, but has a few cameos in Season 2 . </Li>
