My old microwave emitted a sound energetic enow to be heard over the TV, wot is in a different room, but the current one just has a feeble little beep like the Road Runner on Mogadon. Doubtless someone of a Kimmish disposition could wire it up to TowersNet such that it shouts “Kevin! Supper's ready!” through the distascope's audio output. That someone is not me.
