I find it interesting how people find toilets humorous. Maybe toilets have that perfect level of taboo - not talked about in polite company, but not overly disgusting when it is mentioned. It is also a nearly universal theme, which makes it funny to way more people. I love the pic of the Roman public bathroom. It just goes to show that things have not changed in all these years. I have seen public restrooms in this day and age that looked less sanitary than those that are about 2000 years old.
