What about the droid attack on the Wookiees? is a memorable quote uttered by Jedi Master Ki-Adi-Mundi during a council meeting. There was a lot going on then and he just had to get it off his chest. It is also used as a reaction image when someone is forgetting something, whether important or ironic. It can also be used to signify that no one cares about something that somebody brought up. It can also just be put somewhere for fun when there are a great many things going on.
