JW returns with a simple add a letter to the start of a phrase to create a new one, with a humorous definition. As with any puzzle based on humor, YMMV. I was Greatly impressed at the inclusion of 2 grid-spanning fill that worked. I would guess one of the 15 letter fill popped in his head, and this puzzle followed. He also included some very sparkly fill: ROADSIDES, I'LL GO NEXT, RADIO DIAL and ONION DOME a term which I did not recall. I found a hidden treasure but that might just be a product of the pain killers. We will now examine all the evidence....
17A. Domestic shamelessness? : GALL IN THE FAMILY (15). The ground breaking TV SERIES (0:56) gets re-purposed with a an impudent definition clue.
26A. Near giveaway at the liquor store? : GIN FOR A PENNY (12). In for a pound...they do sell many of the airline size bottles at my local liquor store but no GIN and not for a penny.
41A. Fort Knox? : GOLD DOMINION (12). I doubt if Jeffrey had this BREWERY in mind when he chose Old Dominion as his seed phrase but I like the juxtaposition.
53A. Result of way too many leaves in the eaves? : GUTTER CONFUSION (15). This is my favorite themer, both the rhyme and the picture painted by the clue/fill. Maybe he started here?
Okay on to the rest...
