Synchronicity

Last night I was just switching channels when I noticed something strange had happened.

The channel I was switching from was advertising a product that eradicated a huge proportion of bacteria. The one I was switching to was plugging its evening of back-to back episodes of a programme.

The slash shows where the channels changed. This is what I got:

"...kills 99% of bac/to back episodes."

Couldn't do it on purpose no matter how hard I tried.
