My answer wasn't red. That's not surprising since I never think of red first. A deep royal blue or an eye-piercingly bright lime green are my typical first choices for color. The tool part is a little embarrassing. My first thought was of a brain. Not mine, of course. I was thinking of useful tools. It was in a jar and it was blue with lime green squiggly lines running through it. After I thought of that, I immediately wanted to take it back. How stupid could I be? Obviously, the correct answer would have been Tool (the band).
I demand a retest. (Hush, Abby. I'll get to you in a minute. This is important. Just soak in your formaldehyde for a bit longer.)
