That's what I get for not looking it up online, like a normal person

This is good for a chuckle—

I had looked up the number of my local appliance parts dealer in the phone book, then set my cell phone down on the page while I wrote the number on a piece of paper. I then closed the phone book and put it away— with the cell phone in it. Not seeing my cell phone around, I used my desk phone to make the call. When I realized my cell phone was missing, I called it. Since I had the phone on vibrate, not ring, all that paper cushioned the vibration nicely.

Fortunately, I did eventually think to look in the phone book.
