Simon recently rediscovered his magnet barn toy that he got from the WI Rybas for his first birthday! It's got magnets that make five different animals, with one magnet for the head and one for the, um, other end. You put them together in the barn to make a match. After you put the magnets in, you push them like this:

Simon sometimes makes matches, but he prefers making silly combinations.

After you push the magnets in, if they match, the barn sings a song praising you for putting them together. If you mismatch them though...

it sings a very funny song! In this case, it sang "You put a horse in front, you put a pig behind, put them together, and what do you find? A horse pig??? That's SILLY!"

Simon finds it hil-AR-ious when it tells you "That's silly!"
