Decent Monday theme and Monday puzzle. Nice nod to EDNA (19A: ___ Krabappel of "The Simpsons") who (Marcia Wallace) died recently. And the clue for PSIS (10A: Greek letters resembling tridents) in that same area was a nice change from a plain old "Greek letters," or the like. SIDEBENEFIT (11D: Secondary advantage) was a nice 11-letter entry, and the symmetrical 8s weren't bad either. My favorite of those was probably EXPELLED (9D: Kicked out).
All the bumper sticker starters were perfectly acceptable. We've all seen all of those.
Lots of little nuisances in the grid, with MITE, GNAT and ANTS, but no real complaints.
