humour

a characteristic (habitual or relatively temporary) state of feeling

whether he praised or cursed me depended on his temper at the time

a message whose ingenuity or verbal skill or incongruity has the power to evoke laughter

(Middle Ages) one of the four fluids in the body whose balance was believed to determine your emotional and physical state

the humors are blood and phlegm and yellow and black bile

the liquid parts of the body

the quality of being funny

I fail to see the humor in it
