All India Backchod was trending on youtube a year ago, they posted a lot of spoofs to make fun of people to entertain the audience.There was one episode in which Alia Bhatt herself participated to make fun of herself of the poor GK she had, later on which she realised was a very bad idea.
An air hostess episode I saw it was a direct aabuse to the air hostess professionals who do their duty seriously, I am sure it hurts people while making fun of them.It is less active these days.
