Just wait untill he's old enough to make his own lunch but doesn't tell you. You smell something burning but can't find anything and because you had an electrical fire three weeks before and had the fire department out you panic and call them again. Just as you hear the fire sirens you discover a hot dog and three chocolate chips burnt to a crisp in the microwave but it's too late to stop the fire trucks. You are red faced but the firemen have a good laugh and do some checking just in case because they remember being there before.
LOL...now thats the kind of stuff my daughters did. Never had the fire department out though! 8>)
