The slabby face between two cracks left of Sardonic Smile hosts a contrived 5.11+ sport climb.
Thin moves on this route require bearing down on small and sometimes painful crimps and occasional pockets as you solve a thin face mental puzzle, while maintaining the discipline to avoid the cracks on either side of the 5' slab you're climbing on. (Grab a crack, even once, and you're downrated to 5.9, or 5.10 or or something like that.) The crux is at a thin section near the last bolt that requires tricky footwork to a reach. Using the cracks/aretes makes for an ok 5.9/5.10 sport climb.
Because of the low-angle aspect of the climb, this route is less pumpy than other 5.11s at BONP, so you have time to figure out which tiny hold to use next.
