Rajesh Kumar has always come across as a sweet and well behaved boy. He is still well known as Rosesh Sarabhai from the cult comedy series Sarabhai Vs Sarabhai (Star One). Most of his other roles have also been that of a good obedient son. His maiden co production debut Chintu Chinki Aur Ek Badi Si Love Story (SAB TV) wherein he again played a simple small guy who loved Chinki (Divyanka Tripathi) but was very scared of his elders, ended a few months back on SAB TV.
