Sitamarhi, Oct 27 (PTI) Hitting back at Nitish Kumar, who yesterday mouthed a limerick set to a film song to attack him, Prime Minister Narendra Modi today likened JD(U)-RJD-Congress alliance to "three idiots", advised the Chief Minister to perfect the art of "Mushaira" and practise it at leisure after the Bihar polls.

"I have been noticing that Laluji entertains well and Bihar is getting some entertainment after many years. But these days there is an intense rivalry going on between Laluji and Nitishji on many issues--protecting the criminals, doing nepotism, breaking off from truth. Now the competition is also in the field of entertainment.

"Yesterday, I saw Nitishji doing some Mushaira. He felt that he will call some courtiers and journalists, recite poems and defeat Lalu by starting a new form of entertainment. I knew there are three partners in the grand alliance--Congress RJD and JD(U). But I wonder why Nitish Babu chose a song from the film Three Idiots for his first Mushaira. Even if you wanted to parody a poem why did you think of the Three Idiots," Modi said addressing a rally in Sitamarhi.

Kumar, the grand alliance's chief ministerial candidate, had yesterday mocked Modi for not keeping promises and his frequent trips abroad using a song from Bollywood blockbuster 'Three Idiots'.

"Bahati Hawa sa tha woh, Gujarat se aaya tha woh, kaala dhan laane wala thaa wo, kahan gaya use doondho. Humko desh ki fikr sataati hai, woh bus videsh ke daure lagaate hain, humko badhti mahangai satata, wo bas mann ki baat sunata. Har waqt apni selfie khinchta tha woh, Dawood ko laane wala tha woh, kahan gaya use dhoondo," Nitish had said, parodying a song from the film.

(He was like the blowing wind, from Gujarat he came with promise to bring back black money, where has he gone? Find him. While we worry about the country, he travels abroad; While price rise bothers us, he tells us only his 'mann ki baat. Always busy clicking selfies, he promised to bring back Dawood. Where has he gone? Find him.)

Hitting back, Modi said, "What a game of entertainment Nitish Babu! You still have a week's time. Spend it doing this. Call your four-six courtiers, hold a Mushaira.

"Practise it, perfect it, you will get many opportunities after November 8 (the day of counting). You can then sing at leisure songs of your suffering and shed tears ruing why you left someone, why you joined someone. Keep writing poems on all this and keep shedding tears," Modi said.

He was apparently referring to Kumar breaking ties with BJP in June 2013 after being together for 17 years following Modi's appointment as his party's campaign chief for the 2014 Lok Sabha polls and then joining hands with his arch rival RJD chief Lalu Prasad for the Assembly elections in Bihar.

Asserting that leaders of the the anti-BJP grand alliance have "panicked over impending defeat", Modi accused them of taking to "lies, cheating and betrayal" and repeatedly attacked Nitish over his meeting with a tantrik (occultist).
