Burnt Toast, try Burnt Croissant
Some fool who clearly had never eaten a warmed croissant in his life decided he would be his flaky pastry delight in the microwave - for 5 mins.
Cue Fire Alarm, Building Evacuation, no flames sadly, plenty of smoke though.
Needless to say the poor fellow was educated that 10 seconds is normally fine, 15 at a push.
