The funny 'fat girl' you mean is called Tun-tun, she has acted with mehmood as well.
Where is Rajpal Yadav on the poll?? I think he is an extrememely good comic actor, he was in Hungama, Ek aur ek Gyarah, Mujhse Shaadi Karoge, Main Madhuri Dixit Banna Chahti Hoon & Dil Bechara Pyar ka Mara!
From the poll, my vote goes to Johnny Lever!
😆
