Alright, so around 2012 I was looking up Kaley Cuoco's IMDB profile and I noticed she had been on an episode of the X-files when she was way younger. If I remember correctly the episode was the one about cockroaches. Anyway, I watched the episode and there she was. She looked the same except she was a teenager. A very small part. I thought it was an interesting early career part.
Years later I'm looking at her IMDB profile and it's missing. Google searches turn up NOTHING. I'm living in an alternate universe.
