One from the hefty tome of "Seph can't cook to save her life".
So, couple of years back I had a microwave/grill/oven combi. Was on some pretty serious painkillers and a bit out of it. No... a lot out of it. Decided I fancied a cheeseburger. Put the burger under the grill. Cooked it for 20 minutes. Was practically salivating at the thought of a delicious cheeseburger. Something smelled not quite right but I didn't really notice. Burger looked a lot smaller than it should have done... again didn't really pay it too much attention. Put some crisp, fresh lettuce on the bun, slice of cheese... carefully placed the burger in the bun, put the top on, took a bite... almost broke my jaw.
In my heavily medicated state I'd forgotten to set the combi to "grill" and left it on "microwave". So I actually microwaved a raw beefburger, for 20 minutes on full power, into the state where it looked, and tasted like a hockey puck.
Yay. >_<
