### Is Car Talk Invading My Turf?

On Saturday, my friend Mark Stevens emailed me the following joke:

What is the ratio of an igloo’s circumference to its diameter?

Eskimo pi.

Until now, this joke never appeared on the MJ4MF blog, though a similar joke appeared in a post on Pi Day 2010. This joke does, however, appear in the list of 57 conversions in the “Conversion Chart” on pages 65‑67 of *Math Jokes 4 Mathy Folks*.

The subject line of Mark’s email was “Car Talk Mathy Joke.” I initially thought Click and Clack were pilfering my material, but a quick search for “conversions car talk” revealed that they had posted a list of 37 conversions on the Car Talk web site in May 2000. Not that I could have done anything, anyway. The list that appears in *MJ4MF* is not original. Conversions like this have been floating around the Internet for at least a decade.

However, at least one of the conversions in *MJ4MF* was a Vennebush original:

16 ounces of Alpo = 1 dog pound

In looking through the Car Talk list, I noticed one conversion in their list that was absent from mine:

The first step of a one-mile journey = 1 Milwaukee

(You have to put a certain drawl on the right side so it reads as “one mile walky.”)

My favorite joke of this ilk, which did not appear on the Car Talk list…

2000 mockingbirds = 2 kilomockingbirds

I rather enjoy these corny jokes. In fact, I used the following joke last month at the Virginia Council of Teachers of Mathematics’ (VCTM) conference:

Some people are frustrated by metric conversions, but not me. For instance, if you want to know how many televangelists are equal to one expatriate poet, the conversion is rather simple…
