Here is the best I've done at a series of smart-ass answers in the style of Harry Dresden. This example is from our "House of Cards" campaign set in Boston.
To set the scene, the wealthy young wizard Erasmus Thorne (my character) has been imprisoned for a crime he did not commit. He escaped via the Nevernever to clear his name, leaving a glamoured double back in his cell. Among other adventures, he and his friends have rescued his family's maid Ginny, who is actually some kind of supernatural creature.
=============
Raz Thorne and his little sister Hypatia had just finished escorting the Thorne maid Ginny (whose true form is apparently some kind of sea serpent) to the Charles River where she transformed, jumped in, and disappeared under the surface. They are walking back to Longfellow's brownstone through the deep snow in a blizzard. It is in the middle of the night, perhaps 4 am.
On the way back, a shape steps out of the shadows to place itself directly in their path. Raz stops and puts Hypatia behind him. Hypatia peeks around her brother.
The shape draws closer. "I know that it can't be you, because I just confirmed that you are still in your cell." FBI Agent Joe Yexe steps into the illumination provided by a street lamp.
"Do I know you?" Raz asks.
"What are you doing out in the middle of the night in this weather?" Joe presses.
"We're out taking the family sea-serpent for a walk."
"What about the other person who was with you?"
"Took a refreshing little dip in the Charles. One of those crazy ice-swimmers that you see in beer and soft drink commercials."
"And you're carrying her clothes back because..."
"It's laundry day."
