On the sets of the comedy 'Krazzy 4', the entire cast used to go into splits, thanks to funny man Suresh Menon's antics and jokes. Directed by Jaideep Sen, the film stars Arshad Warsi, Irrfan Khan and Rajpal Yadav.

But whom does the master of comedy find funny while shooting?

'I used to laugh a lot with the killer timing of Irrfan and Rajpal who was always with full energy. You know Irrfan bhai looks very serious but he has a great sense of humour with perfect timing. He just killed me with his humour,' said Menon.

Well it seems that apart from his stellar acting, Irrfan has quite some untapped funny energy in him too.
