Boa-constrictor

I'm being swallowed by a boa-constrictor
I'm being swallowed by a boa-constrictor
And I don't like it one little bit
Oh, no, he's got my toe
O gee, O gee, he's up to my knee
Oh, my, Oh, my, he's reached my thigh
O fiddle, O fiddle, he's at my middle
Oh heck, Oh heck, he's up to my neck
O dread, O dread, He's got my GULP!!!
