How is it meant to be funny?Ok, yeah...I'm not sure what you watched, but ok. The big goofy eye design for the robots is there, not sure how you don't see that.
Around 7:26 a robot flies into view, looks back and forth at the two walking along some kind of pipe, and drops out of view really fast...all while making little robot noises. It's meant to be as if some guy came upon two people fighting; did some big exaggerated head movements while going "wha'" or "huh", and then ran off all while screaming or something...it's meant to be funny. Even the fucking piping is making cartoonish noises.
They have faces because all droids have faces. Even the GNK Power droids.When Anakin jumps on that robots head at around 9:46, that's meant to be funny too. Why do you think we get a close-up of just the robot looking around like it can't believe someone just jumped on it's head? Why do you think those robots even have something that looks like a face? It's so we as the audience can pick up on these moments. If you can't get this than maybe...and I can't believe I'm saying this, maybe George Lucas was being too subtle.
Vidocq is right. You're bitching to bitch. Let's assume you're right and it's meant to be funny. I suppose it didn't bother you that Threepio was being funny during the scene where Han's being frozen. I mean, it was a serious scene and all. Or how about Threepio being funny while everyone's trying to stop Boba Fett from taking off. Or when they're trying to get away in the Falcon. Or when the Hyperdrive is finally fixed.
