Clue/Question: He scaled Yosemite’s “El Capitan” without a rope, which had onlookers – – –
Answer: CLIMBING THE WALLS
(The zenith of stinky puns? The culmination of years of pun-tificating? Yes, the boys have reached a new height in groan inducing Jumble answers. Possibly their peak performance. Their crowning achievement of cajolery. Could there be a capper? Of course! They regularly outdo themselves.
All of today’s clue words are known commodities. The jumbles “sloas” and “cabone” appear to be new, with “lirgl” and “limwed” having definitely been used before. The answer letter layout was an imposing thirteen letter jumble. Very cryptic, indeed.
Towering cartoon of “El Capitan”! You could get vertigo just looking up at that escarpment. Forget about looking down! I’d love to see Yosemite someday. Be well and do good, friends.) — YUR

The onlookers at “El Capitan” were transfixed
with the Climber who was attempting to scale
the mountain without a rope. They wanted to LASSO him down with the mising line.
They tried to think of the Climber as a “BEACON of Light” to get back positive thoughts. For the moment, they were “CLIMBING The WALLS” in fear. If they stayed in the same place any longer MILDEW may start festering on them!#**
They were already late for their cookout, new
GRILL and all. {liquid & solid}
PS. UR, ZenitH of stinky puns!!^, Pun-Tificating* & PeaK performance.>>^
Bring out the dice and “Rock N’ Roll”….

5/4/19: “watching the scale “might have been cute.
Yeah, Cat. They would have had to alter the clue/question to “climbed”, but that could be an appropriate answer to that cartoon. With a few different letters of course too. — YUR
