Ren Hoëk Faces

On Saturday I was drawing what I can only describe as incredibly repressed-looking men with a friend for an upcoming short we're working on together.  For inspiration I turned to an old episode of Ren & Stimpy called "Stimpy's Invention" directed by John K which originally aired back in early 1992.   How has so much time gone by already?
Anyway, for those who aren't familiar this is the episode where Stimpy becomes worried that Ren is always unhappy and thus invents a Happy Helmet for him to wear.  I've never seen happy faces drawn with such unwilling intensity & misery... some of these shots made for perfect references:

I'll try to post the full clip when I have some time...
