"What do you say?" Message On 20th October 2015 @ First year class

It was not planned at all, I just entered the class room by 4.00PM and wanted to remain there to send off all the first year students of my dept. Who were in two sections.
Suddenly, as often,  i got the preacher in me started to push myself to start and go ahead to talk something as that follows below,
" I went to the black board(actually green) and wrote,

'0 0 0 0'

and 

asked those kids(1st year students) what is that, I wrote ?
Someone said zero, 

to another i asked and he said, letter O, and another said  4 letter O, at last someone said 4 zeros.
OK now, i told that the last answer was on my boat! yes it is 4 zeros.

I immediately  puzzled them saying, " let me give you these 4 zeros and in return you give me back some number other than ZERO (I added) you can add, subtract, multiply, divide or do any such operations "

( students starred scratching their heads, asking each other, looking into the roof, trying to recall those operations they studied )

While students trying to answer my puzzle, I interrupted again saying, "Before answering my puzzle, tell me what is impossible in this world??"
As expected that forerunner told "Nothing"

Immediately thrown the next task to her, "OK if nothing is impossible, then touch your nose with your tongue, or lick your elbow"
( everyone one were having "Naak out" )

Once they tried and failed, "I asked her(the girl who answered me nothing) to answer me now is nothing impossible still ?"

Since i broken her words she said something are impossible, as i expected.

I reacted to her response by giving the clue for my question that i posted to them at the beginning,
the  clue is that the answer of operating  0 0 0 0 using one of the operations gives us the answer as 4.

[Before going further in between some one creatively told that without using any operators at all he found a way. He said, " put a zero below another zero and becomes 8 ".( actually i was blown coz of his creative problem solving ability)"]

After the laughs and shying settled, I gave the answer 0!+0!+0!+0!=4.

"Ohhhooooooo. . . . .,"the students said.

Now i explained that girl who answered     "nothing is impossible", she was correct before.

"If I could make zeros into some numbers there are ways to make all the zeros in our life into something. "

"There are ways to create something from nothing."

If you find the way, practice in it you can actually touch your nose with your tongue, lick your elbow, and 

very importantly, , ,!! "Do many things irrespective of your past experiences and failures."

1. Though if you are a guy from Tamil medium school, You can talk great English (Winglish).
2. Though you got low score in board exams, You can shine better in college.
3. Though you got to be poor now, You can reach heights with sear determination.
4. Though from a science background, You can become master in programming.

The following was the last question to them

What is not possible?, they said in harmony, " NOTHING " 

Now, What do you say???
