It always happens when it rains.

I was driving my old plow truck just to charge up the battery since it had been sitting for a few days. As i was heading down a state hwy it starts to bog and stuble a little. I let off the gas and the bang, I was like holy **** my wife jumped out of her seat. The look on her was was priceless. Anyway there was the terrible noise kinda like a grinding but also like a torch cutting. Well the engine spit the #4 clylinder spark plug out and it was sparking off the frame. Well we limp home and I go to change the plugs and break off 2 more in the block.
Of course this was all done in a freezing rain, gotta love Illinois lol. Anybody else got that bad luck feeling too???
