Transformers: Prime

You know what would be neat? If Raf and Bumblebee both 'spoke' correct American Sign Language, and then there were subtitles for what they were 'saying'. Sign Language doesn't get a lot of portrayal in mainstream media. Then Raf could explain that one of his siblings is deaf or something, so his family knows ASL. They could do it in a way that is mildly educational but not preachy. Then, at least, they'd be addressing a real world issue in a respectful way, and the subtitles would let everyone else know what is going on.

(As for why Bumblebee is using ASL.... uh... he learned it from the internet.)
