right on schedule. It's "America strong." This guy just brought this huge box, look at it. Reporter: There are few things that gets kids more excited than delivery boxes, especially big ones. 5-year-old Olivia and 2-year-old mkenna excited to see what's inside.

And "I miss daddy." And "I miss him so much." Reporter: So Sarah had an idea, hide her husband in a box, to make the surprise return even sweeter. But she had some obstacles to overcome. My husband is really tall. He's 6'5", so how are we going to get a box that big? Reporter: It took 2 1/2 boxes, lots of tape, and a secret plan. He snuck in the back door, I put him in the box. As soon as I heard them come down the stairs I crouched down. I had the biggest grin on my face. Reporter: And here it is again. Daddy, daddy, daddy, daddy! Tears of joy, just being able to surprise my kids like that. Reporter: A one of a kind gift they'll never forget. Can you give me a kiss? Yes.
