If your printer keeps jamming, open it up to remove the gray and white eraser that was dropped in ... probably by the 2 yo.
If the VCR (for those who still have them) keeps ejecting the VCR tape, get a flashlight and look inside to find the matchbox car, toy plastic plate, or colored pencil that was pushed into it ... probably by the 2 yo.
If the toaster smells like it's burning up, unplug it, then look inside and remove the bread wrapper twistie-tie or butter knife that's been dropped inside ... probably by the 4 yo.
Or, you could lock the 2 yo and 4 yo in a safe environment and never let them out of this room which has no electronic equipment at all. Though I have no idea how you'd get anything done if you had to spend your time in this electronic-free environment with them. Sigh.
