Data is excited about his friend Keiko's upcoming wedding to Chief O'Brien, where the android will be giving the bride away. When the bride succumbs to jitters and calls the wedding off, Data applies android logic, and decides that since O'Brien loves Keiko, if calling off the wedding makes her happy it will make O'Brien happy. Of course, the heartbroken groom's reaction to Data's news quickly reflects otherwise. Data's confusion is compounded when Geordi assures him that the wedding will proceed as planned. With this in mind, he attempts to buy a gift for the couple, and encounters Worf, who informs Data that he will have to dance an the wedding. Data has never danced, so he enlists Dr. Crusher's help -- after learning from her file that she was once a tap dancing champion.
