Allow me to introduce you to the Schmidt Sting Pain Index.
I wish to carry out independent experiments into this, and think Himesh Reshammiya would be an ideal guinea pig. I wonder if the bullet ant would be enough to induce a nasal scream.
Of course, if Himesh started singing “Aap Ka Surroor”, I suspect the bullet ant would feel more pain.
