What is K??

I vividly remember the incident that Krishnan is talking about, but I can't for the life of me remember if it really happened. Is this another school legend? - like the one where the Govt official walks in and insists that people open the windows and let the environment come in, or the CS teacher who said that he had two daughters, both of whom were girls.

But Krishnan nails his imitations of Ajoe and Salim sir. Ajoe'd always adjust his tie when called upon, and Mr. Salim did talk (and stand) exactly like that.

Ah good times. He did a pretty good Kookie too.
