Hephaestus
Hera realized her mistake of throwing Hephaestus off Mount Olympus and wanted Hephaestus back.  Hephaestus politely refused, saying that he was quite happy where he was. Hephaestus denied because he knew that the only reason that Hera wanted him back, was because he could make her items. He then set to work and fashioned a beautiful golden throne and sent it to Hera as a 'thank you, but not really' gift. Hera felt delighted by his present. The instant she sat on it, golden ropes and chains flew out and tied her into the chair.
