Mumbai : Vatsal Seth, who shared screen space with Tabu in `Toh Baat Pakki', says he had fun on the sets when he sang "Ruk Ruk Ruk..", the famous dance number from the leading lady's 1994 film.

Tabu, who played an older sister's role, took Vatsal and Sharman Joshi under her wings and looked after them on location. She regularly gave tips to Vatsal on how to handle his scenes.

Vatsal one day mustered the courage to break into Tabu's "Ruk ruk ruk" dance item from the film `Vijaypath'. "That's quite true. At first I was quite intimidated by Tabu. I mean she is...My god! The ultimate. But as we shot for the film far away in Ooty where there was no life except shooting we began to know her better. Far from her stern, aloof image, Tabu is loads of fun when you get to know her," Vatsal said.

There came a time when Tabu and the two boys were totally at ease. That's when "Ruk ruk" happened. "We were playing antakshari with the boys on one side and the girls on the other. When I got a chance to sing a song beginning with 'R' I saw it as a god-sent. I had been waiting to sing 'Ruk ruk' to Tabu. It was one of my favourite songs on television when I was younger," recalled Vatsal.
