Did he forget to drop the rock?
Gee, I’m starting to go down. Better drop the rock.
Hold my beer and gimmie that rock!
I’m goin’ for a swim....
I doubt he forgot to drop the rock, most likely he was trying to bring the rock back to prove he had done whatever feat he was attempting. I am sure once he got into trouble he dropped the rock but it may have been too late.
Not knowing enough about the facts, since this is just a sensational headline with no real details in the story, that’s my guess.
Also glad to see the general respect for the dead and humanity posted here. Sigh.
