Get the Jewish Spaniel Madness (JSM) mug.
JSM or Job Security Measure is used by IT professionals everywhere to ensure they don't become irrelevant. It was made famous by a particular IT professional in the late 80s when he foresaw the coming Cloud and realised the only way forward was to become extremely relevant. His resulting piece of work, JSM for People Who Haven't Got A. Clue, is the defining document on how to avoid becoming irrelevant. Many IT professionals the world over, with no time to waste investing in training and certification have often found this book on JSM to be the way out of being intelligent
That was a terrific JSM you deployed on the network, very smart.
