The mix is a little wonky, but here are the lyrics:
I've got a secret to let you in on
I had to wait until I got to know you
it's not the kind of thing you want to begin on
but I think that now it's time to show you
Right through this door is where I'm working on it
my secret project that I hold so dear
it's not a robot and it's not a bonnet
but every day I want it to be near, it's my
portable marshmallow roaster
that I made out of human bones
it's better than a campfire or toaster
but if you make too many you will be all alone
I thought of this in my high school math class
while trying not to learn geometry
the teacher caught me looking out to the grass
and said "son, stay after and see me"
So I did and continued to ignore him
until the time did come that h e let me free
after which I began to bore him
a new hole in his skull, which is what you're seeing with me,
chorus
you can put one on each side of the jaw bone,
and fill the cavity with kerosene,
the jaw hinge works as a flint for a lighter,
and the constant fire assures that it all stays clean
I hope this secret doesn't really disturb you
I assume that I can have your trust
Unlike the others that I've shown my secret basement
that you're looking at, now keep your mouth shut, you must, after
seeing my
portable marshmallow roaster
that I made out of human bones
it's better than a campfire or toaster
but if you make too many you will be all alone
