I remember that one from a long time ago..but as I recall, they were not that nice...
BELLY BUTTON BRUSH
Start with a popcycle stick, cut in half. We use terry cloth stuffed with a little batting for the belly brush to be glued to the stick. Print the verse and staple it to a bag holding the Belly Button Brush.
Verse #1
If Your Belly Has Lost It's Lustre
Try Our Belly Button Duster
Verse #2
If You Have Belly Button Lint
Please Keep It To A Hush
But Do Take This Little Hint
A Belly Button Brush
Verse #3
For Those With Everything
And Even Worth A Mint
Here's A Belly Button Brush
For All That Fuzzy Lint
PUT A SMILE ON SOMEONE'S FACE
