I just thought of one that I find both hilarious and to fit the concept of being "subtle."

I can't remember what movie it was in, but Charlie Sheen was playing some deadbeat down and out type of character. And another character said something to him about doing something right, and Sheen responded ~"Yeah right, I can't even shave my sideburns so that they're even."

Then later in the film I noticed that his sideburns were, indeed, uneven. I found that to be a nice subtle addition to the character, that they actually had him shave them uneven. The combination of me laughing at the line originally and noticing it to be true later really got me.

It may not be 'great,' but at least it's subtle.
