I'm huntin for a flash animation that was done prior to 2004. IIRC it had similar animation to 'How to Kill a Mockingbird' and had the following song,

Let's sing a song about safety,
'cos safety is pretty important!

You should look both ways,
Before crossing the street,
And don't hop out,
In front of that jeep!

And watch out for the giant lesbian,
Who lives in the sewer.
She'll grab your leg,
And you won't get away!
'Cos her grip is too strong,
She works out every day.

She'll wear your flesh and eat your bones,
I guess you should've stayed home!
I guess you should've stayed home!


I think it had more than just the song so I'm hoping it's still on the internet somewhere.
