The X-Files, Season 7

Agent Short:
I see the money bleed out, but it just doesn't seem to make the results of your work any better. So many of the cases you investigate are left unexplained. Makes it hard to justify the expense.

Scully:
So much of the work that we do cannot be measured in standard terms.

Agent Short:
How would you measure it?

Scully:
We open doors with the X-Files, which lead to other doors.

Agent Short:
Doors leading to... "A conspiracy of men who cooperated with alien beings to create human alien hybrids." So we could all become slaves of an alien invasion.

Scully:
I believe that there was once a conspiracy. I believe I was taken by men who subjected me to medical tests, which gave me cancer and left me barren.

Agent Short:
But you don't believe in aliens?

Scully:
I've seen things that I cannot deny.
