Yeah I start one of these regularly maybe once or twice a year (when I'm drunk)
Previous offers have been fairly pedestrian stuff but it certainly brings out the weirdos on here.
Tonight not weird but I fancied a roast dinner - clearly pissed and no capacity to cook one. I've just put a frozen hash brown, two tablespoons of frozen peas, two tablespoons of Bisto, several cocktail sausages and a massive dollop of horseradish in a Sports Direct mug with some boiled water. Microwaved it till it was nearly on fire. Absolute lush. Roast dinner in a mug.
Genius/troll?
I have fond memories of MNers mashing up bananas with wotsits on serving spoons and the like
