  • Ugh. That is completely tasteless. Not that I approve of them, but at least I understand the purpose of calendars full of nekkid, or nearly nekkid women. I can't imagine anyone buying a calendar of dog piddle.

  • I think it's supposed to be ironic. Sort of a parody of all the countless (very specific) calendar themes out there. I mean, there are whole stores that sell nothing but calendars. Millions of artsy pictures of things that surely no one could care about. So I can see the humor in a dog poo calendar. Doesn't mean I'd buy one though.

  • This word is from the Latin kalends, which meant "debts are due", which also referred to the first of the month. Apparently, Rome was more similar to us than we thought.
