Clever frog ;)

Once a woman went to the pet store to buy her husband a gift on the 23^rd of February, she decided that is must be an animal.  But everything that she likes was too expensive . Then she went to the dealer and asked to help her to find something cheaper.
– Well, - said the seller - I can recommend you great giant frogs. They are quiet, friendly, and tell you in secret, they are trained to do pleasant things for men! We have sold 30 frogs already.  - That’s great! - Said the woman - I’ll take it.
And thought to herself: “If this is true, then I finally get rid
from this tedious duty. ”
At home, she was presented with a gift to her husband and told
him about the outstanding capabilities of frog. But he did not believe her and is wrapped all in jest … In the middle of the night the woman was awakened by a clatter of pots and pans. She rushed to the kitchen and saw that the husband and the frog study a book about tasty and healthy food.
- What are you doing here in the night? - She asked.
- If the frog will also learn to cook, - said the husband with glowing eyes - You will leave the house! Valentina
