Dragon Ball Kai - episode 65 - 17 Jul, 2010

Android #18 fights with Super Saiyan Vegeta and wins easily. Super Saiyan Trunks tries to help his father, but is also easily defeated and gets his sword broken in the process. Piccolo and Tien then get beaten down effortlessly by Android #17, while Krillin stays behind and watches the horror, and Android #16 simply observes the nearby birds. After the fight, the androids leave, but before they do #18 kisses Krillin on the cheek. (Source: Wikipedia)
