We toured the battleship "Missouri" while we were in the Pearl Harbor area, and my son (he's 10) bought a small replica of the ship.
He realized just a bit later that he has a larger version of the "Missouri" already, from the days of playing w/ big ships on the floor.
So, after he unpacked, when I stepped on a teeny helicopter hiding in the oriental rug, I asked if it came from the smaller model--" Is this from the mini Mighty Mo?"
Here's my favorite story about that mini Mighty Mo.*
My son got stopped by the x-ray folks at airport security on the way home. They saw a long, skinny, slightly-pointy-on-one-end metal shape in his luggage.
Once they found the model and rescanned it, they put him back in line.
I joked, "You can't bring a battleship on an airplane! It's a weapon!"
*how do you style a ship's nickname?
