Never under estimate a Kid week end joke?

On a Sunday Tanaka's parents were betting the condition was the looser will pay $10.

Mother to Father I bet you can't do laundry better than me.

Father did very fast and won the bet

Mother to Father. You can't clean toilet better than me.

Father did very fast and again won $10.

Tanaka was playing video game but listening everything.

Again Mother to Father, I bet you can't clean home better than me.

Father once aging proved his superiority and won the bet.

Mother to Tanaka, what did you bring here?

Tanaka to Mother, This is my saving box. I also want to bet.

Tanaka answered calmly, I am going to bet on all my saving that is $150. 1$ bill each he mentioned this too.

This gave a shocked to parents and they insisted that Tanaka should withdraw but Tanaka insisted on betting.

Now it is Tanaka's turn, Tanaka to Parents, I bet you can't do my homework better than me. Winner will get $10.

Mother won the bet easily.

Again Tanaka to Parents, I bet you can't clean my shoes better than me. Winner will get $10.

Again Mother won.

Tanaka to Parents, I bet on my saving which is left to total $130. If you loose each one of you

will pay me $130. If it is ok with you I will ask a question?

Parents accepted this bet and Tanaka to Parents, What is that I can do but you two can't?

Parents started thinking and they answered a lot and every time Tanaka said No,

Finally parents said we give up.

Parents to Tanaka, Ok son, please tell us what is that you can do but we can't? tell us will you?

And Tanaka replied, "GROWTH" I can grow but you can't grow any more.
