It's just funny to me that the article is acting like it's Wal-Mart's fault.
Clearly some kid figured out the phone code to get on the loudspeaker.
Reminds me of one time when I was about 16 myself. I had a friend that was "one of those guys".
He got on the speaker and said "Attention Wal-Mart shoppers: I jacked yo daddy's dick!" (a catch phrase of his for whatever reason).
He was tackled by security before he could complete the last syllable and brought to a back room. The other two of us (I believe it was Taylor and me), just kind of waited around the back of the store where they took him. After about 30 minutes we had him paged to the front, then after about an hour we had to ask what happened to our "mildly retarded friend". They had taken him to a holding cell in some other city.
He's banned for life from all Wal-Mart, Sam's, and Lowes stores in the country.
