The place where I work decided to provide company-paid cell phones to the "suits" upstairs. After negotiating a deal with a cell phone company, we arranged for the phones to be sent to the homes of the various VIP's.
The day after delivery, I received a call from a partner screaming about how his cell phone didn't work. He said he charged it overnight just like the sheet said, but in the morning, it wouldn't power up.
I asked EXACTLY what he did with the phone when he got it. "I took it out, plugged the charger into the wall and into the phone."
"Did you put the battery in the phone?"
"Not the extra one."
"Sir, the phone only came with one battery."
(Pause) "Oh, I think I figured out what's wrong with it."
