To say about anything about national integaration is not better than to watch TarakMehta Ka Ulta Chasma.Hindu Muslim Sikh Isiai slogan are always uttered by netas and teachers but in a Tv serial like this is unbelievable.No doubt comedy is always there .People enjoy the comedy of course The dialogue are simple and make you brust into laughtee your mood will be refreshed.Jetha lal and hie wife Daya Bhabi are alway in tension popat lal worried aboiut his marriage and the above all Tarak Mehta a well known HINDI KAVI says all the problems in style.But I think its more than National integeraton to comedy
