Gabbar Singh has been our most loved villain. His "Arrre Oh Samba!!!" and the rider to the dialogue "Kitne Admi the..."is probably the most easily remembered Bollywood dialogues. I have my own theory, that his love for Sambhar and the thought that he would have to share it with other "Admi's" prompted this question, but lets keep that aside for now.
His popularity was probably followed by the legendary Ambrish Puri(Mogambo!!!), and the remaining minions in the roles of serial murderers, kidnappers and smugglers with a million thugs on their team firing away machine guns that couldn't hurt a mouse, even if it were the size of the incredible Hulk and tied to a wall post.
