Story of that old snake in the grass, called The Viper

I was in my apartment all alone when I heard a ring tingling on the telly-phone
I said: Who's that at half past three? And a frightening voice came back at me!
Sss! Sss!
I am The Viper! I'll sssee you in seven weeks
My head was spinning and my knees were weak
I could hardly stand on my own two feet!
It's next call let me out of bed
And how I flipped when that voice said
Sss! Sss!
I am The Viper! I'll see you in seven days
I shook like Jell-O in a hurricane!

My heart was pounding like a Pullman train
Again that voice upset me so
Again I flipped as it said: Oh, oh!
Sss!
I am The Viper, I'll see you in seven seconds!

Now I'm certain that my time has come!
I can hear its knock; it's too late to run!
I know that I must let it in!

So wish me luck, 'cause things look grim!
Sss! I am The Viper!
Oh, why have you come?
I have come to vipe your vindows!
