A man wanted to get something nice for Meg, his blonde girlfriend, so he bought her a cell phone and carefully explained all of its features.
The next day, Meg went shopping. Her phone rang and, to her astonishment, the call was from her boyfriend. “Hi Meg,” he said, “how do you like your new phone?”
Meg 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.” “What’s that, sweetie?” he asked.
“How did you know I was at Wal-Mart?”
