A young man wanted to get his beautiful blonde wife, Susie, something nice for their first wedding anniversary. So he decided to buy her a cell phone.
He showed her the phone and explained to her all of its features.
Susie was excited to receive the gift and simply adored her new phone. The next day Susie went shopping. Her phone rang and, to her astonishment, it was her husband on the other end.
"Hi Susie," he said, "how do you like your new phone?"
Susie replied, "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 though..."
"What's that, sweetie?" asked her husband.
"How did you know I was at Wal-Mart?"
