Fun theme today. Letters missing from the clues combine to spell part of the answer that describes a feature of the fully-spelled clue. How's that for complicated? It was much easier to figure out than it is to explain. For example, the clue for 36A is R_od_ Isl_n_ Red. The missing letters in the clue spell HEAD and a Rhode Island Red is a chicken, thus it's a HEADLESSCHICKEN. Pretty neat. I thought TIRELESSWORKER (22A: _ax_ d_iv_r) was the most amusing, but HAIRLESSDOG was the best because the clue was so bare (54A: _ _rr_e_)
BADASS, OPINE, and SHRED share the grid with the old favorites EELS, ERR, EPEE, and ADO.
