Do you have a carrot?

Rabbit comes to the bookshop:
- Do you have a carrot?
- No, it's a bookshop.
Next day rabbit comes to the bookshop again:
- Do you have a carrot?
- No, I told you - it's a bookshop, we don't sell carrots.
Next day rabbit comes to the bookshop again:
- Do you have a carrot?
- No! If you ask me one more time, I will nail your ears to the wall!
Next day rabbit comes to the bookshop and asks:
- Do you have nails?
- No!
- Then, do you have a carrot?
