Has anyone here got fed up and started hitting the IDK button when expected to know the answer everyone else's problems? How did that work out?

As we all know it is common for apps and server people to just pawn there issues off on the network and we have to figure out the problem. Sometimes it feels like we have to know more about how everyone's stuff works more than they do. I just had to explain to an exchange administrator that the mystery IP with 5k connections to his server was another one in the cluster. They didn't even know what cluster IPs they were using between their servers. What happens if we just start acting as dumb as they are and say IDK to everything? Do they get forced to learn or do we just look like butt heads?
