Notice oven is hissing, remove overflowing roast from oven, dunking the top of oven mitt in juices, gingerly lift aluminium trays (always double up for these instances) into small amount of free bench, slopping juices into groceries in bags below bench, tip excess juices off under tray and rinse, gingerly tip juices out of tray (willing to sacrifice potatoes at this point) and load back on under tray. Flip meat, smoosh a potato or 2 and shove back in oven. Lose will to live, consider vegetarianism.
