I don't want to sound ungrateful but....
I think of the premium characters, Hank is the only mute. It's always weird when you're sending everyone off on their tasks and one doesn't speak when you tap them. I usually have just what they'd say...

I've noticed that some of the phrases the characters say when tapped on are from old Simpsons episodes. I also remember reading that the files for Milhouse's voice over are in the game files but not in the code or something.
