Anakin built C-3PO??? How utterly ridiculous. I guess Shmi just took him with her whenever Watto sold her?
Isn't C-3PO a protocol droid, well versed in all the customs, fluent in over 6,000,000 forms of communication? Wouldn't it have made more sense storywise for Threepio to be in the diplomatic service, either on Naboo, with the Jedi, or even with the Senate?
Of course, Owen doesn't recognize him in ANH. Oh yeah, different color scheme, yeah, that's right... sure.
One would think that an R2 unit would be easier to build from scratch than a humanoid protocol droid, but that's just my opinion.
C-3PO's lines in the OT are still all pretty funny and come from the character and make sense (especially in ANH and TESB, ROTJ has a few groaners, but I'll forgive them) However, the whole putting his head on the battledroid was such a pathetic farce: "This is such a drag"??? (I'll bet GL laughed his head off when they came across that part in the first cast script reading, though I am sure the rest of the cast and crew just started inspecting the creases in their pants.)
