I don't think I ever ran as much as I did after I got [Ricky] Ponting in Sydney . It just comes naturally in the moment; you can't plan such things. Generally it depends on how important that wicket is and how vital it was in terms of turning the game. Sometimes I laugh at the celebration when I see it afterwards. The other dismissal that I liked was when I had [Paul] Collingwood caught and bowled in Mumbai  when I dived to my left. I was full of energy. There were a few catches that got dropped and I took a beauty. So once I took that brilliant catch, I took off and charged towards the crowds.
Virender Sehwag, because he hardly defends anything. In the 2001 series Matthew Hayden was quite tough. Brian Lara was very difficult to bowl to. I didn't get to bowl much against Lara, but Hayden was more difficult in that series because he made big runs against us. Though Lara was definitely a much better batsman than Hayden. After 2001 I had a good measure of Hayden and didn't allow him to dominate much.
It is very difficult to explain in words. All a youngster can do is lock his wrist and try to roll the ball over, making sure the seam position is towards the slips. The doosra came by chance to me - I was experimenting during my days at the Sports Authority of India Academy in Chandigarh, around 1996.
In Tests there has been more than one, and all of them came when the team was looking for someone to perform well lower down the order. One such innings was against Australia in Bangalore in 2008, when we drew the game. Then in the same series, in the final Test, which we won. I also enjoyed the knocks in Sydney and Adelaide in the 2007-08 away series. Earlier in 2009 I got a 60 against New Zealand and we would have won the Test if the rains had not arrived.
I've got lots of friends. Maybe I'm everyone's best friend! Shane Warne has always been there whenever I've asked him for any sort of help as a bowler.
No, no, no. I don't think I have the physique to be a fast bowler. I wouldn't have survived for 11 years as a fast bowler. I do it for fun in the nets at times, and chuck if I want to hit someone on the head!
The Oval. Maybe because I've played for Surrey. It is a true pitch with a lot of bounce. I wish I was bowling during the final Test of the 2009 Ashes - I would've got a lot of wickets.
Muralitharan. Being a spinner myself it is easy to read him from the hand and understand what he is doing, but it is still difficult to face him as a batsman.

I won the show so that means I was the better dancer, isn't it? I don't think Sreesanth would like it, since he was comparing himself to Michael Jackson. And I'm nowhere near that league. I don't enjoy proper dancing but I like jumping and shaking my hips to songs like "Dhan Te Nan…"
It has to be Michael Hussey in the Bangalore Test. There was a spot outside his off stump that I was trying to hit every time from wide off the crease and round the wicket. The plan was to bowl at least four balls in that spot and make him play the other two, hoping he would miss or give a catch to the close-in fielder. He hit one doosra for a six over midwicket. So I pushed the fielder at short midwicket deep, with a short leg, so that if he attacked or defended I had a fielder in position. And I started to bowl doosras frequently. The ball that dismissed him was another doosra. It cut in so much, as if it was a legspinner, and bowled him. I couldn't believe it myself.
You have to back yourself every ball and make sure you don't give away easy runs. You can't ever make the batsman feel that you are going to pitch at length within his range, because he is already thinking of hitting you.
Offbreak, fast and slow offspinners, the doosra, topspinner, skidder. The hardest delivery has to be the stock ball because you have to bowl it regularly and make sure it lands on the seam every time and goes where you want it to go.
I would like to finish with 600 Test wickets at least. Usually I set my targets match to match and try and achieve them.
