The Diversion

In reference to Make your Own Greeting Card post, brohemian Simon commented via Wiki:

“Public reference to bodily functions such as urination and defecation is taboo in many cultures and thus arouses intense anxiety in many people. For this reason, there is a whole sub-genre of humour, toilet humour (also potty humour or bathroom humour) based around excretion. This genre is particularly popular with children. For that reason, it is particularly taboo when adults use it, though it is quite common.: - Wiki

Is toilet humour funny? debate in the comments…
