You can say a lot of things about Lauren Conrad, but not having a sense of humor isn't one of them. "The Hills" star guested as herself on Sunday night's episode of "Family Guy," along with fellow castmates Audrina Patridge and Whitney Port (Spencer — depicted as a talking orangutan from "Planet of the Apes" — did not voice himself).

In the episode, titled "We Love You, Conrad," Brian (the talking dog) winds up having a brief fling with the L.A. fixture, who surprises him by being a certifiable genius. Her relationship with Brian quickly sours, however, as Brian realizes that Lauren — depicted reading classical literature, spouting off terms from molecular biology and re-creating the terraforming world from "Star Trek II: The Wrath of Khan" — is smarter than him.

With Conrad leaving the show that made her a household name, time will tell whether she makes "The Hills of Quahog" her new home. If so, she would join a wealth of other Hollywood celebrities who make regular trips to the popular Fox series, including Adam West as the town's mayor and James Woods as himself. If this marks her only appearance on "Family Guy," that wouldn't be surprising either. The show regularly employs one-off guest stars, which have included Jennifer Love Hewitt, Luke Perry, Molly Ringwald, and most recently, the entire cast of "Star Trek: The Next Generation."
