The Ken-Koh Effect- the natural law that whenever something doesn't work and you want to show it someone it always seems to resolve itself when the second party shows up.
I took my car into the shop because it was making a grinding sound, but the KenKoh Effect struck again and the repairman couldn't hear the problem sound!

The program wasn't working but then Paul walked by and BOOM! Everything worked perfectly! The KenKoh Effect strikes again.
