It wasn't Whitney, but one of my friends read this on a summit register:
"Everyone else freaked out and turned back. Final score for today: Mountain - 10+, Hikers - 1" - random guy
"I hope you made it back" - arrow pointing to the entry above

And on another different register:
"F*** Donald Trump. Black lives matter" - random guy
"Politics and hiking don't mix" - entry below responding to the guy above
