One sunday morning – Jince kuttan got up early and called ICICI customer care. Lady on the other end asked for phone banking password.
Jince: it…is… ‘ITC124′…
sweet voice: Sir, the password is wrong, I’m sorry…could you please repeat?
Jince: I’m also sorry dear, new password is “ITC 121′…
Sweet voice: Sorry, wrong again… This will be your last chance…
Jince (after a few mins of silence) : CLUE, please… 
That was a good joke. Nicely written.
