The cast is different for different episodes. they all put up a nice show but they could put in more effort at making things more interesting
the plot of their varies around the daily day to day happenings that we all can relate to, putting humour to sarcasm, they manage to display complete entertainment within 5 to 20 minutes of a video.
I have many a time observed in their various episodes that they use the idea put forth by the viewers very skillfully, using the ideas from viewers they make a storyline to work on.
the direction and the camera effects, all seem very skillfully undertaken.
