Cell Phone

A young man wanted to get his beautiful blonde wife something nice for their first wedding anniversary. So he decides to buy her a cell phone. She is very excited, as she loves the new phone. He shows her how to use it and customize all the features.

The next day the blonde goes shopping. Her phone rings and it's her husband, "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 Wal-Mart?"
