With a breakfast pizza laden with bell peppers, bacon and ham, mozzarella, eggs and "butter sauce" and another pizza combining pepperoni, pineapple and jalapenos, Crispy Crust (3111 Glendale Blvd., L.A.,  661-3111; 1253 Vine St., Hollywood,  467-2000) does a decent job of bringing the bizarro factor.
But the hands-down winner of weirdest pizza in L.A. belongs to Koreatown's Mr. Pizza Factory (3881 Wilshire Blvd.,  758-0077).
Mr. Pizza specializes in pies made with a sweet potato crust that's filled with a sweet potato mousse. It's very mad scientist, but once you liberate yourself from convention, it's easy to love the thick, fluffy, orange crust.
The best pizza is the Potato Gold, featuring hefty potato wedges and sizable bacon slices.
Far weirder is the Grand Prix, injected with a sweet, crumbly paste that wouldn't be out of place on a cobbler and accompanied by strawberry dipping sauce that could double as waffle syrup. The menu recommends eating the crust as dessert, which is perfect for those who don't mind bacon, Cajun shrimp and jalapenos coexisting with raisins.
Forget the standard thin-crust pies. Ignore the bulgogi pizza (it's closer to hamburger than anything resembling Korean barbecue). At Mr. Pizza, the stranger the better.
