I saw this lila in a movie a couple of years ago and wanted to share the story, as I remember it:

Satyabauma had a desire to have Krisna as her own exclusive husband. For this she prayed to Narada Muni for to grant her wish. Narada Muni said, "I will fulfill this desire if you give Krisna to me." Satyabauma did so readily. For a time, it was funny to see Krsna following Narada Muni about chanting, "Narayan, Narayan...." Soon Satyabauma became worried that she had made a drastic mistake and organized all the queens to collect all their gold and add it up in order to buy Krsna back. Frantically, the queens gathered their golden crowns, bracelets and chains and brought it fast before Narada Muni, and so then Narada Muni pulled out the largest set of scales. Carefully he assisted Krisna onto one side and had the queens stack their golden attire onto the other side. All witnessed that the gold was not enough to buy Krisna. Soon Rukmini had an idea, as she retrieved a Tulasi leaf from the temple rooom, lovingly inscribed Krisna's name on it, and tossed it gently on top of the pile of gold. Now the scales had tipped, and all cheered, "Krsna is ours!"
