Something I love bringing up again from time to time: a little more than five years ago a friend and I found a functional microphone in a smart kitchen appliance that wasn't advertised to have one. The product in question was being promoted hard by Lidl because they sold it at a fraction of the price of similar devices.
It made national & european news and I was interviewed by the biggest TV news show at prime time.
All we wanted was run Doom on the thing. We installed Discord on it and hopped into a call because we thought it would be funny and fell off our chairs when it turned out the person on the other side could hear us just fine
