I know of a lady who whilst working for a Darwin operator was issued with the fluro earplugs for in the cockpit use.
Apparently they taste terrible and even though they look like lollies, shouldn't be eaten.
Wasn't the same one who flew a 210 to an 'outport' location with a tow bar still attached to the nose wheel! taxied in after an uneventful landing without realizing the mistake until a line of junior pilots stood staring in disbelief at the said 210
