Here's a clue to y'all who are tempted to write "get's": It's almost never, ever right. And I say "almost" here in the same sense as you're "almost" at risk of being killed by a Transylvanian blimp. You'd have to twist the English language to the fringes of insanity for it to possibly, ever, be right. (That is, you'd need to figure out a justifiable way to make "get" a noun.) And you're not that good. You're just not.
Don't. Write. "Get's".
Ever.
