I think half my cels fall into this catagory.  
But here's one of my current favorites from 
Detective Conan.  This is what's written on my 
webpage: This is my new favorite Conan cel! It's 
from the fourth movie, "Captured in Her Eyes", 
from the wedding party scene. Setting up the 
scene: Kogoro is frustrated because none of the 
police officers will tell him anything about the 
murders of two detectives. Detective Takagi is 
standing nearby, and Conan mentions something to 
the effect of "By the way, Mr. Takagi likes 
Detective Satoh, doesn't he?" at which point 
Kogoro grabs Takagi by the lapels and 
says, "Oooh? That's very interesting. Let's go 
tell Detective Satoh about Takagi's feelings!" I 
LOVE the sweat and the color in Takagi's cheeks!! 
Of course, he breaks immediately, and tells 
Kogoro what he knows about the case.
