Terrible Two’s Tough

Spring writes in with..

Attached is a picture of apostrophe abuse on the new Reynolds Wrap commercial. It claims its product is “terrible two’s tough”, inadvertently making the claim that “terrible two IS tough.” Whatever THAT means.

I haven’t seen the commercial, so maybe I’m missing something, but even without the apostrophe, what does “Terrible Twos Tough” mean? Are you supposed to wrap your kid in the stuff when he starts acting up or something?
