> I was in tears laughing from an exercise of simply playing peekaboo

My wife and I have a 15 month old and one of our favourite games is for one of us to sit with him on the stairs looking through the bannisters at the other one dancing and singing. Sometimes we are all in absolute hysterics. Humour is very much about a collective will to engage in the shared enjoyment, and I reckon most parents would agree with me.

But yes, OP's article does not really cover satire, parody, toilet humour, slapstick, deadpan, cringe humour etc...
