Jacques offers to teach Marge Simpson to bowl after she receives a bowling ball for her birthday. He is captivated by Marge and slowly tries to woo her. While at brunch, which Jacques explains as "not quite breakfast, not quite lunch, but you get a slice of cantaloupe at the end". Jacques finds the courage to ask Marge back to his apartment in Fiesta Terraces. Though this happens off-screen, he presumably ends up alone when Marge chooses to stick with Homer. It is unknown what happens to Jacques after this. Marge believed that his last name was "Brunswick", because it was engraved on his bowling ball yet that was really only the brand of his ball.
Jacques is somewhat of a Casanova and mainly seems to try to seduce his clients instead of actually teaching them anything. In later episodes he can be briefly seen. In Burns' Heir he is seen kissing Edna Krabappel on a secret camera. The footage is briefly seen in Burns's Surveillance Room.
