Let's be honest, white Christians lag a little bit in the technology department. But that doesn't prevent them from exploring the wonders of technology... without really knowing how to use it.
Just like all other human beings, white Christians love their cell phones... but an inordinate percentage of the white Christian population unfortunately doesn't know how to silence them. At a crucial point in every church service, a cell phone WILL ring. Unfortunately for all involved, not only will the cell phone ring, but it will do so at a rapidly increasing volume to the annoyance of all in the sanctuary other than (apparently) the owner of said cellular telephone.
While the expert level white Christians may have ring tones from popular songs currently playing on Christian Radio stations, more than likely, something like the "Mexican Hat Dance" will interrupt the most spiritually charged moment of the worship service.
