What was your most "Harry" in-game moment?

[Leatherneck]

While not very spectacular, still Harry-ish.

The Half Demon US Marshal is driving everyone in his BMW.  Not really his, as it was supplied by the US Marshal service having been confiscated and turned over to the Marshals.  The wizard was using thaumaturgy to track an wounded and fleeing Chuprakabra.  While driving around trying to corner the beasty, the tracking spell remained running.  First the car developed a slight knock.  Then the CD player started to skip with the Marshals favorite CD playing.  Eventually the Marshal was started to suspect that the wizard had something to do with his odd playing CD.

The next hex aspect was the Marshal players idea.  He tried to eject the CD, but it wouldn't eject.  Nor would the CD player turn off or lower the volume.  To make matters worse, it started to play one song over and over.  The one song on the album the Marshal disliked and tended to hit the skip button rather than listen to.  The remainder of the chase involved a half demon glaring at a smirking wizard.  And the Chupra got away, because no one wanted to get wet slogging through a bayou at night.

That definitely reeks of Harry's Luck.

I've got a wizard character who has a special talent for summoning random things from the never-never. Basically he is a green lantern rip-off. Last time around, I had him summon skateboard riding rattlesnakes while yelling "EXTREME!"

Also there was a reference somebody made to Miley Cyrus being a changeling and getting her voice from a Gruff family member. Her singing sounds Ba-a-a-a-ad!

And another encounter with a male WCV that led to a friend's male character yelling "BAD kind of threesome! Bad! Kind! Of! Threesome!" before running out of the room.

The PCs are sitting in the office of someone who they're pretty sure is not human (Bald, 6'8" and 500lbs of muscle) and clearly a major power in the area discussing stategy after the bad guys just tried to re-kidnap someone they just rescued. 

PC: "Hey, I remember hearing about some guy advertising as a wizard in Chicago.  Maybe he can help us?"

Big Scary Guy: "That man is not coming to my town!"

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."

Traps, lethal ridiculous over blown villan traps and walking into them because it made sence at the time. My GM did a swinging pendulum of doom it was amusing.
