As a matter of fact, everything tastes better cooked over an open fire. 
The one day you decide that you don’t need to bother taking a shower because you’re not planning on seeing anyone that day is the day that one of your attractive friends decides to show up unannounced.
You put-off washing the floor until all the grotty guests have gone, then after the ritual scrubbing and cleaning, manage to break a bottle of tomato ketchup all over the gleaming surface. Guaranteed.
Terrible things DO happen in threes. Your car will be involved in a serious accident, your oven will break down and your refrigerator will cark it during a heatwave, all in the same week. Murphy’s Law sucks really. 
The day after you buy that wonderful computer/television/sound system the bugger goes on discounted special for half-price.
The week you give up meat/alcohol/smoking/smelly cheese, the ‘authorities’ decide that those things are actually beneficial to your good health.
Your cat will only walk across your keyboard if your computer is switched on.
They’ll take my smelly cheese when they pry it from my cold, dead hands.
Cats are always on the wrong side of the door.
