I was checking out some of review for sunil grover I found that -he is a best stand up comedian. First of clear your doubt he is not a stand up comedian he plays dramas and act some roles which are very much famous they are as-
Dr. Gulati
Rinku bhabhi
Gutthi
Piddu
And even some extra on some occasions like if they have some new guest in show , he transform himself into a new look with new drama nowdays due to some rumours or reality( who knows) is in news becouse of fight with his friend and host of kapil sharma show i.e. kapil sharma
He has an awesome and magnetic personality
You will get alot influenced by his interviews that why he has chosen comedy as his dream for it,
He is a real time performer, u can see his epic comedy timming in show ( tkss) and he has a high sense of what audience like. In his real life is not a perdon who speaks alot he keeps quiet untill he asked on some topics we can see it in an interview where kapil sharma was asked some questions on his Sydney tour and if u see sunil in that interview he has Stick himself to a corner of table and seems like he is enjoying some scenery .lol! https: //youtu.be/FVjU1wsacqQ
