Oh back in the 90s these character actors on shows were everywhere. Armin Shemirman (probably Biggest role was Quark on Deep Space Nine) was in everything from like Principal in Buffy the Vampire Slayer to like a little Weasle politician in SG1. But my favorite clip of him is at a convention "So you've been on every sci-fi and fantasy show in the last decade which is the worst set you had to work with?'

"Oh what was the name of that one with three Bitches?"

'You man Charmed the one with Three witches?'

"Yeah that's the one. Any studio that let's three actresses be Executive producers at the same time is gonna cause problems."
