Having just watched the first season of Mary Hartman & the TP Episode where Dick & Andy break into the adoption agency to steal Nicky's file, & realized that Mr. Brunston, who "catches" them, is played by Will Seltzer: Davey the "mass murderer" on M.H.!!!  I know, amazing, huh? If anyone needs me, I'll be looking for "a life"...

The whole notion of actors actually being employed and appearing in many different television shows and movies is mindblowing. I mean once is enough, right?

But that kind of "recycling" seems to be common in the Twin Peaks cast.

Ooooh, that's why when Dick says that little Donny is dead he puts that "how the hell did these bastards find out" face... He probably was reaching to his Walther PPK (it's obvious Josie didn't shoot Coop) in his pocket before Dick corrected himself...
