From Dilbert, we derive The Numbing - the null state following that terrible moment in which you know that there's nothing you can do, and you might as well be fine with that.
In a support context, this is most frequently experienced in a conversation that goes something like this:
Consultant: We've invested $1512 million and 27,000 years in the development of this system, and it's all based on the clever and unique assumption that blue is red.
SP: (gulp) Did you just say you needed blue to be red for this to work?
Consultant: Yes, and... (pause) ahhhh...
SP: Um... Read any good books lately?
