Someone ought to test this Shelton guy and see if he can remember which home Allen supposedly did this to so the owners can be tracked down to determine if anything like that ever happened.
Several observations here:
1. Boys will be boys.
2. Everyone has used the "N" word, people need to get over it.
3. It was a really crappy, small-minded trick, if it's true.
4. Boys grow up to regret some of the stupid stuff they did as kids. If this really happened, I bet Allen regretted it a long time ago.
