Bollywood superstar Shah Rukh Khan would not like to take any sides on the controversy surrounding the AIB roast as he feels humour is a tricky thing and will always invoke different reactions from people.

When asked about the celebrity roast involving Karan Johar, Ranveer Singh and Arjun Kapoor, the actor said he believes in humour but has also become careful with his words as an entertainer. "I am someone who has always believed in sense of humour. Over the years my sense of humour is rounded off if not completely over. I have learnt to curtail it because there is always going to be a thin line when it comes to humour. It is always going to invoke radical reaction, either you are going to laugh at it or hate it," Shah Rukh told PTI in an interview.

"When you are a popular actor like I am, people listen to you... So, you need to relook at it and I am only speaking about myself here. There will always be issues and questions. I can't take any sides."
