FEARLESS LEADER = Franklin Delano Roosevelt minus the letters F E A R — in that order! A wonderful find. I've been searching for an exemplary "clues are missing certain letters" concept for years now, and this is way better than anything I've come up with. It's so easy to identify FDR's name even without those four letters, so that you have half an idea of what's going on — and then when you get the other half, it's transcendent.
After solving that one, I thought for sure that this would be the POW! The fact that FDR was a FEARLESS LEADER makes it perfect.
HEADLESS CHICKEN was close in terms of wow factor, H E A D perfectly omitted, while still keeping Rhode Island Red identifiable. I did hear some complaints the last time the phrase showed up, making me wonder if it doesn't have universal recognition (running around like a headless chicken = going in chaos).
Oh, how badly I wanted the rest of the puzzle to measure up to these two findings. ODORLESS GAS was fine, although it's not as easy to smell what _xygen _iflu_ _ide should be, and it wasn't immediately clear to me that oxygen difluoride is an odorless gas.
TIRELESS WORKER had some issues too, as a TAXI DRIVER is a worker, but I don't know that all TAXI DRIVERs are tireless.
Huh. Now that I think about it, is oxygen disulfide odorless? Was it just a coincidence that FDR was a FEARLESS LEADER? I think so, which takes away from my perceived cleverness of the theme. Drat.
HAIRLESS DOG was the one that yanked it right out of POW! contention. _ _ r r _ e _ is … a HARRIER? How is the jump jet a HAIRLESS DOG? I read up on Harriers for five solid minutes before wondering, could there be a dog breed named the HARRIER? Huh.
The gridwork also pulled down the solving experience. As much as I crave bonuses like BADASS, RASSLE, BJORK, EMOJI, it's much more important to deliver a friendly Tuesday solving experience for newer folks. Entries like OJO EPEE SLO don't do that. Having LEPER in your grid isn't great, either.
Such a shame. FEARLESS LEADER is one of those amazing finds that rarely comes along. Cutting out HARRIER to let the grid breath more, and working to upgrade TIRELESS WORKER would have made the puzzle Puzzle of the Year material.
