Refusing to comment on the lows, he said, "I don't want to say now. After I actually quit, I will say."
Chatterjee served as Speaker in one of the most eventful Lok Sabhas which saw many controversial debates.
On the worst moments of the 14th Lok Sabha, Chatterjee said, "July 22, 2008 when those notes were shown."
He was referring to the cash-for-vote case, when three BJP MPs displayed wads of cash in the Lower House and accused the UPA government of offering bribes to MPs to win the Trust Vote.
Chatterjee, who often expressed his anguish over the misbehaviour of MPs in the House and at times even threatened to resign, said he did not find anything amiss in being called a "headmaster".
