Boa Constrictor

I'm bein' eaten by a boa constrictor,
 a boa constrictor, a boa constrictor,
I'm bein' eaten by a boa constrictor,
And I don't like it a bit. 
Oh no! He's got my toe. 
Oh gees! He's up to my knees. 
Oh my! He's got my thigh. 
Oh peanut butter and jelly!
 He's up to my belly. 
Oh heck! He's reached my neck. 
Oh dread! He's got my .  .  .   slurp -- slurp!
