*Car Talk* Puzzlers

I make a point of not having heroes, but there are people I greatly admire. Tom Magliozzi, the co-host of *Car Talk* who passed away yesterday, was one of those people.

Not only was Tom able to make other people laugh, he was always laughing himself. He and his brother Ray hosted *Car Talk* from 1977-2012, making folks laugh — and think — for 35 years.

In case you haven’t noticed, laughing and thinking are two of my favorite activities.

Every week, Tom and Ray would try “frantically to come up with a mediocre new puzzler,” a logical or mathematical problem that wouldn’t have an immediately obvious solution. Sometimes I’d be able to solve them, sometimes I wouldn’t, but I’d always enjoy them… and I’d laugh out loud while Ray read the puzzler and Tom offered commentary.

Below are two of my favorites, but you can find the full list of puzzlers at the Car Talk web site.

This first one sounds so simplistic, but most folks get tangled up in the details. Share it at your next department meeting, and see how many colleagues can solve it. You’ll be disappointingly surprised!

A store paid $6.75 for a shirt, and they then sell the shirt for $12. A man visits the store, buys the shirt, and pays with a $20 bill. The clerk gives the customer $8 in change, as expected. But unbeknownst to the clerk, the bill was counterfeit — instead of Andrew Jackson’s picture on the bill, it’s got Michael Jackson’s! In total, how much did the store lose on the entire transaction?

That one reminds me of the Marilyn Burns horse problem: You buy a horse for $50, sell it for $60, buy it back for $70, then sell it again for $80. Did you make money, lose money, or break even?

This next one is a classic that’s taken many forms. Finding a solution isn’t too hard… finding the simplest solution may take a little effort, though.

You have a four-ounce glass and a nine-ounce glass. You have an endless supply of water. You can fill or dump either glass. You can measure six ounces of water using these two glasses. What’s the fewest number of steps in which you can measure six ounces?

RIP, Click. I’m sure you’re already making people laugh and think upstairs.

### 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…
