Deputy Chairman P J Kurien also asked Singh a few times how much time he is going to take to complete his reply.
As Singh took pains to answer the points raised by each member who participated in the over eight-hour debate on the Home Ministry's functioning, opposition members pointed out that a member to whom he was replying was not present.
Members in the opposition benches were seen gesturing at each other displaying their impatience while those in the treasury benches were seen enjoying the opposition's plight.
Sitaram Yechury (CPI-M) said the government has indeed tested their patience and it is a "good strategy" to "tackle" the opposition.
Many opposition members turned impatient to leave the House and some who wanted to seek a clarification from the minister were goaded not to do so.
Minister of State for Parliamentary Affairs Prakash Javadekar also sent a chit to the Leader of the Opposition Ghulam Nabi Azad, that brought smiles on the Congress member's face.
