Childrens' Safety Song

My son, who is six, was recently required to learn a short song about crossing a street safely.

(Sung to the tune of, "Mary Had a Little Lamb")
Look before you cross the street, cross the street, cross the street.
Look before you cross the street; Left, right, left.
Stop and look before you cross,
To stay safe each day.

Look before you cross the street, cross the street, cross the street.
Look before you cross the street; Left right, left.
Stop and look before you cross,
To stay safe each.

My son was less than impressed. I am fairly certain that if he didn't already know how to cross the street that this little ditty would not have taught him how. So, (because I am an awesome dad with good parody skills) I came up with an alternative that is catchier, has more memorable lyrics, and that my son actually likes.

(Also sung to the tune of, "Mary Had a Little Lamb")
Look before you cross the street, cross the street, cross the street,
Look before you cross the street,
Or you'll get hit-by-a-truck!

Guts and organs all around, all around, all around,
Guts and organs all around,
That used to be in you!

Nothing left but a bloody smear, bloody smear, bloody smear,
Nothing left but a bloody smear,
Drying in the sun!

Now there's a song with a message that sticks with the listener.
