Boa Constrictor

I'm being eaten by a Boa Constrictor,
A Boa Constrictor,
A Boa Constrictor.
I'm being eaten by a Boa Constrictor,
And I don't like it one bit.

Whadaya know, it's nibblin' my toe.
Oh gee, it's up to my knee.
Oh fiddle, it's up to my middle.
Oh heck, it's up to my neck.
Oh dread, it's mm-mm-mm-mm...
