"Do your eyes pop out?"

I call Alistair "my little goofball" since he is so silly.  Here he is singing a song he learned at school today.  He was being so silly that I couldn't understand what he was saying, so I asked him to sing a little slower the second time.  He makes me smile everyday.  (He makes me want to pull my hair out every day too, but that's not very entertaining.)

These are the song lyrics:

Do your eyes pop out?
Do they bounce all about?
Can you tie 'em in a knot?
Can you tie 'em in a bow?
Can you throw 'em o'er your shoulder
Like a continental soldier
Do your ears hang low?
