The Bosco jingle is familiar to many of my parents' generation:
I love Bosco
It's rich and chocolatey
Chocolate-flavored Bosco is mighty good for me
Momma puts it in my drink for extra energy
Bosco gives me iron, and sunshine vitamin D
Oh, I love Bosco, that's the drink for me!
A popular filk
version goes as follows:
I love Bosco, it's full of TNT
Mommy puts it in my milk to try and poison me.
I fooled Mommy, I put it in her tea;
now I have no Mommy to try and poison me!
