Home Depot has recalled nearly 4,000 Homer all-purpose bucket mugs due to a fire hazard. When microwaved, the silver-colored bucket handle accent decoration can spark. No injuries or damage have been reported.
If you own one of these mugs, the US CPSC recommends that you stop using it and return it to Home Depot store for a full refund.
OR just keep it on your workbench and use it as a pen/pencil/random tool catch-all. Or just be sure not to stick it in the microwave.
