There is a website, Porcelain Poetry, devoted to toilet humor. Not humor from the toilet. But funny toilets. Imagine, grown men and women engaging in such puerile wit. And yet the potty has been a comedic mainstay since medieval times. Chaucer adored the water closet and even Wikipedia has a notation:
Toilet humour is popular among a wide range of ages, but is especially popular with children and teenagers, for whom cultural taboos related to acknowledgement of waste excretion still have a degree of novelty. The humor comes from the rejection of such taboos, and is a part of modern culture.
I do not have an affinity for such things, but I have saved this photograph that I took at a friend’s wedding reception years ago. What do you give the couple that has everything? His and her commodes.
