If you ever get the great idea to throw some bacon on the grill while you're making chicken for dinner, don't neglect to put it in a pan.
And be sure to have a fire extinguisher handy to put out the fire that will certainly occur if you don't.
Also be sure you clean the grease and extinguisher gunk off the grill while your husband is still at work so that he'll never know. If you're feeling really ambitious, you can clean the house really well so if he does notice that the grill is awfully clean he'll think that you did it because you ran out of things to do inside the house.
Not that I would know anything about this, of course!
