What shall I call them?

Would you mind calling the police?
What shall I call them?
Would you like to ring 999?
I’d rather ring a bell
Shall we get an ambulance?
I’d prefer a cat,myself
Shall we go to A and E?
Rather go to B C D
Do I need stitches?
No, we all have mouths
My nails are very long
Like hair, they grow
