As you know there are network guys and then there are the others, I heard a small joke about about cisco network guys.
A cisco guy and a appv guy went to a military school, when they got to the shooting training ground, they started shooting some marks a few meters away. The appv guy was very good and hit every time, but the cisco guy just did not hit anything. The appv guy said "why do you miss every time, it is so easy, maybe your gun is miscalibrated." The cisco network guy looked at his gun, pointed it at his finger and shot it of, then looked at the appv guy and said "It works at my end".
Had to share this one with you guys.
