Fringe, Season 4

Dunham:
Do you think this may have something to do with the vigilante cases PD has been working?

Captain Lee:
My thoughts exactly. Local police received a dozen similar reports in the last few months: criminals going missing, junkies mysteriously vanishing, victims calling in claiming that their assailants were attacked mid-crime.

Agent Lee:
Maybe Batman's moved to the Bronx.

Dunham:
What's a Batman?

Agent Lee:
The "Caped Crusader", the "Dark Knight." [sees two confused expressions] Billionaire playboy puts on a cape to clean up the streets of Gotham.

Captain Lee:
Oh, you mean Mantis.

Agent Lee:
Seriously? Your superhero is an insect?

Dunham:
Oh, because nothing says badass like a flying rat.
