Bill bought his beautiful blonde wife, Sherry, a cell phone for their first wedding anniversary.
Sherry loved the gift, and watched intently as Bill explained all the features on the phone.
The next day, as Sherry is having her hair done, her phone rings. It’s Bill. “Hi hon,” he says. “How do you like your new phone?”
“I just love it. It’s so small and your voice is clear as a bell, but there’s one thing I don’t understand. How did you know I was at the beauty parlor ?”.
