### XXXIII for Increased SEO

.

 Beware the Ides of October! Check back on October 15 for a MJ4MF World Premiere!

Today is 10/10/13, or X/X/XIII in Roman numerals. Three years ago, I published XXX Rated to celebrate 10/10/10, and it has consistently been one of my most visited pages. Not surprising. Today’s top searches which led to my blog were:

• xxx sex
• sex xxx
• metric system jokes
• xxx.sex

Well, at least someone was looking for math jokes when they found my blog!

In honor of National Metric Day* and to appease most people who stumble across this blog, here’s a joke that mixes metric and sex. It’s subtle; pay attention.

The metric conversion for 69 is 181.

And another?

What do sex and metric conversions have in common?
I enjoy doing both, but most of the time I do them alone in my room.

And a sorta, kinda Roman math joke…

A Roman soldier walks into a bar. “Martinus, please.”

The bartender replies, “You mean martini?”

The soldier says, “If I wanted more than one, I would have asked for it!”

And finally…

When is 6 equal to 8.5?

In Roman numerals, the number SIX can be translated to 8.5. Remember that IV = 4, because a smaller number (I = 1) precedes a larger number (V = 5). With SIX, S = ½, I = 1, and X = 10. Since both S and I precede X, they should be subtracted: 10 – ½ – 1 = 8.5. Hence, 6 = 8.5. Q.E.D.

* Not an official holiday. See Pat Naughtin’s declaration as well as the U.S. Metric Association Metric Week.

The Math Jokes 4 Mathy Folks blog is an online extension to the book Math Jokes 4 Mathy Folks. The blog contains jokes submitted by readers, new jokes discovered by the author, details about speaking appearances and workshops, and other random bits of information that might be interesting to the strange folks who like math jokes.
