I've always loved that phrase "keep an eye out for ...."
When ... occurs, what good is my eye out of its socket?
It doesn't mean take it out like in remove it.
It means take it out like you would a doggie in the park, so it can play ball, fetch sticks* and sniff around and stuff.
See?
(*Careful with the sticks though, they can have yer eye out them things!)
