Real-life brainteasers–RIPPED FROM THE HEADLINES!

I was just hanging a cheap Ikea clock in my kids’ bathroom. I wanted it centered in the little alcove where the toilet sits.

Height was easy but I suddenly realized I had no way to center the clock from left to right on that little bit of wall between the two corners of (for lack of a better name) the toilet nook. I didn’t want to run downstairs for a tape measure–but I realized there was another solution. What did I do?

(I’m almost more interested in reading other possible suggestions than finding out if anyone else can guess what I did.)

Edited to add: If you ever find yourself in this situation, don’t hit your head and invent the flux capacitor. See the suggestions on this thread.
