This is not about a mistake but a really funny spontaneous moment that happened on tattoine once were me a and a couple of other guys are dancing away showing off, and other people see us and join in, eventually there are like 20 of us dancing away and we were on a spawn spot of an enemy when he suddenly materialised in the middle of us.....lightsaber flew lasers flashed it was over in less then a second and then we all just kept dancing.
