Murphy's law

I have a gas oven and cooktop.  I use mostly the front 3 rings to cook on.  They have an auto-light feature ... ie.  I turn the button and it clicks to light the gas.

Lately, it is having trouble lighting and clicks, and clicks ... and clicks.  Eventually I decide to walk to the other side of the kitchen for a manual lighter.  Sometimes I do it immediately, other times I wait.  

EVERY time I get to the drawer with the manual lighter, it lights automatically.  Yes ... even when I wait longer to see if it is eventually going to light (before the house blows up ...)
