Want to play the oose-a-loose.

The story:

It was Christmas, and I was little. I used to make
Christmas cards for my family, and my brother's just
happened to have that lyric. He came out of his room
in which I left the card laughing and told my mom
and dad what the card said. My mom took me aside and
told me the real lyrics, and so now I laugh every
time I think of it, though I was insanely
embarrassed at that time.
