Former beauty queen Sushmita Sen, who teams up for the fourth time with David Dhawan for forthcoming comedy "Do Knot Disturb", says she never thinks twice before saying yes to the maker of comedies.

"I enjoy doing comedy and David Dhawan is the one who brought me into it with 'Biwi No.1'. So every time I want to laugh and make people laugh, it is with him.

He is always there for me so I end up doing the same," Sushmita told IANS over phone from Mumbai.

"The thing is that since he and Vashu Bhagnani (producer) both gave me 'Biwi No.1', I have pretty much gone with his guts. When he asks me for a film, I just do it. We usually don't get down into the role or anything," she said.
