Scientists at Xero0ne Labs have finally calculated a criteria for evaluating human behavior.
The theorem, named after its founder Ayush Saksena (BE MSc), classifies all humorous or attempted-humorous actions into two categories:
- Tafri
- Chutiyaap
According to the theorem, above a certain limit, all so called nautanki ceases to be Tafri and becomes Chutiyaap. This limit, derived empirically through repeated experimentation on the Maturity Levels of test subjects from the Despo Doodh group, has been named 'The Saksena Limit' in honor of the founder of the theorem.

However, The Saksena Limit is highly stochastic.
It depends on factors such as:
- Whether or not the joke is cracked by Ayush Saksena
- Whether or not the joke is on Ayush Saksena
- Whether or not a girl Ayush Saksena could have slept with would change her mind because of the joke
The current value of The Saksena Limit has been estimated at 0.8 NPM.
Also, when we examine the graph of the derivative of the function, we can notice that there is a steep change in the function near the Saksena Limit, which indicates that a joke intended as Tafri can easily turn into Chutiyaap, if the almighty Saksena so decides.
Thus, we can also conclude that "There is a thin line between Tafri and Chutiyaap."
Chief Minister of Uttar Pradesh Kumari Sushri Mayawati Ji has announced a prize of rupees 1 lakh and four marble statues for the founder scientist Ayush Saksena for this remarkable discovery.
