Here’s some generic stuff to start, maybe:
“I love gold!”
“It wasn’t me!”
“It’s a trap!”
“Look out!”
“Surprise, surprise”
“Are you out of your mind?”
“I feel like the back end of a horse”
“Hide!”
“By your leave”
“Your orders, sir?”
“What are your orders?”
“What do you have for me?”
“What do you have in mind?”
“What news?”
“Hey, that’s not a horse”
“There’s a hole in my boot”
“You look like the back end of a horse”
“Yes”
“No”
“Nope”
“Maybe”
“Certainly”
“Agreed”
“Never!”
“Ok”
