A group of senior IDF military officers were being given a tour at a new high tech military intelligence facility. Itzik, the intelligence officer hosting the tour said the computers in the facility were so secure that they were able to withstand nuclear and chemical attacks.
Suddenly, Itzik saw that one of the officers had a cup of coffee and yelled, “There’s no drinking in this room! You have to get rid of that coffee.”
Startled, the senior officer said, “OK, but why?”
“Because a coffee spill could ruin the keyboards!”
