Seek Self-Help

Toy with strangers in your local bookstore by reaching for the same book they're going for at the same time. Make awkward eye contact to add depth to the experience.

The first time you do this, they'll think it's a strange coincidence. The fifth time, they'll probably want to know what your problem is.

Explain that you're a crazy person who attempts vaguely humorous things you read about on the internet. Works every time.*

*"Works" in this context meaning "confuses people further."
