Which character earns his freedom when Harry Potter tricks his master into giving him a sock?

Dobby the house elf is a loyal, helpful friend to Harry Potter — eventually. At first, he complicates Harry's life more than he improves it. By the Triwizard Tournament, however, he hits his stride, helping Harry finish the second task by providing him gillyweed. Ultimately, he gives his life to rescue Harry and several others from Malfoy Manor.
