'Shit, why did I even decide to do WAC with you? I have to do all the work.' I cribbed.

'What can I do? My mamaji is here', she whined into the phone.

'Oh, thats your excuse today? The day before you had an injured pigeon in your room. Yesterday your excuse was that stupid filthy little dog. Today it is your mamaji. Are you the zoo-keeper of IIM-A?'

'Shut up !'

'And why are you sending me all these links?'

'To read, of course !'

'I am just gonna cut and paste all that crap into a doc file and mail it to the TA.'

'Yeah, do that. And ask her to pick the relevant stuff herself.'

'Okay. I am gonna do that.'

'Yeah, do it.'

Noni and I had started working on the WAC report just a day back and we were already having our third cribbing and complaining session. Both of us were trying our level best to shove the work away from ourselves.

'What are you doing now?' she asked.

'I am mailing her.'

'Yeah do that.'

Playfully, I composed a mail which went like this...

To: radhas@iiimahd.ernet.in
CC: 5jyotia@iimahd.ernet.in
Subject: Our WAC report
Please find attached our WAC report. Please pick the relevant details and grade them accordingly.
Thanks,
Karthik,
Jyoti.

I double checked the TA's address and made sure that it had three i's instead of the two in 'iimahd.ernet.in' and clicked on the send button.

Into the receiver, I said "Check your inbox."

'Oh, you actually sent it !'

'Yeah, I did. You asked me to, didnt you?'

'Yeah. I did.' she paused. I guess she noticed the TA's wrong email address, because she said. 'But where's the attachment? You didnt attach the file.'

'Heh heh. But what if there actually exists and address like iiimahd.ernet.in and it is redirected to the iimahd.ernet.in domain?'

'Yeah. It might exist. Especially given your luck with the TAs!'

'No, I think this time I'll be okay. I have got the returned mail message already.'

'Okay.'

After a bit more of aimless nonsensical chatter, I hung up.


A little while later, Prostee and Atul came to my room and we decided to study a bit of finance. My concentration, as usual, wavered after sometime and my focus shifted to my computer. Aimlessley, I started checking all my email accounts.

One particular mail caught my eye while I was going through my institute email account. I clicked on it and went through the text.
I swore.

The mail went like this...

From: radhas@iimahd.ernet.in
Subject: Re:Our WAC report

I did not receive the attachment along with the mail you have sent. Please resend the same. If you have any queries regarding your report you can contact me at wing 12K.

The last date for the submission of the report is 21st January,2006 4.30 PM. The report has to be submitted as hard copy and a soft copy needs to be pasted in the courses folder same as WAC-I.

Thanks.
Radha Sriram.

'What on earth is this?' I swore aloud.

'What happened?' Atul asked. Prostee looked up from his book as well.

I told them about the little prank I played on Noni, and then showed them the mail. Needless to say, they burst out laughing like crazy.

'Dude. Why does it happen to you all the time?' Prostee said.

Having laughed to his heart's content Atul said, 'Lets check its header. I am sure Noni is playing a prank on you.'

'Yeah, I sort of think so too. You can manipulate the 'From' address in any mail client.'

We clicked on the message's header and as expected the mail originated from Noni's system's IP address.

'See !' Atul exclaimed. 'She has used the client Mozilla Thunderbird to do this.'

'Yeah. I see.' I said thoughtfully. 'Shit. She has the nerve to try to fool me. She'll face the consequences', I paused. 'Microsoft Outlook should also be able to do this sort of a thing, right?'

'Yes, I think it allows you to change the from address. I am not too sure though.'

'Hmm.' I opened Outlook and started composing a mail. After 15 minutes of intense creative activity, I sat back and looked at my extremely technical sounding mail in sadistic satisfaction.

'Hey guys, listen to this.' I read my masterpiece aloud to Atul and Prostee. 'What do you think?'

'Great stuff!' Atul laughed.

'Play a prank on me, huh? I am the bloody prankmaster! She's gonna throw a fit as soon as she reads this.'

'Yeah. It sure is gonna take her by surprise. Eventually she'll find out though.'

'Yes she will. But for a second, she's gonna get shocked. That will do for me.'

'Yeah, that she will.' We laughed aloud and gave each other hi-fives. I sent the mail.


I tried getting back to my work. I read a page or two of finance, but couldnt wait for some sort of a response for that message. I clicked open the sent folder to admire my masterpiece again. I smiled as I read the message for the nth time.

Then something caught my eye. 'Hey! Wait a minute! What the hell is this? Guys, take a look at this.'

'Atul and Prostee came over and stared at the screen. A split second later they were both clutching their stomachs and going bonkers with laughter.

'She...she...' Prostee said in between gasps of laughter. 'She must be laughing her head off at how big a jackass you made of yourself just now.'

The from address of that message read,
'Karthik Laxman [5karthikl@iimahd.ernet.in]; on behalf of; student@actlan.iimahd.ernet.in'
