“There will be wild ......what?”
Seems like the last word is missing from that statement.
The first word is missing from your quote. The President's actual statement was:
Be there, will be wild!
It was “Be there, will be wild.”
Punctuation saves lives.
“Let’s eat, Grandma.” versus “Let’s eat Grandma.”
Grammar is not the President’s strongest suit.
I find it endearing. I say that as a writer and editor.
Punctuation matters.
