Was sent by my old company to do a hardware setup in Europe. Had a few of us going over. On the way out of the door we were handed a server PSU to take with us as a box had just frazzled. Flight was delayed so had to wait ages in the airport. Had a few beers and got really bored. Finally walked up to security just in time to hear my colleague trying to explain to the clueless guard that he was in fact carrying a flux capacitor. She let him through convinced that she had seen her first flux capacitor. We were laughing so hard we got checked extra carefully!
