Thirded. One of the first moments that came to mind for this thread.

Also dig:

I Spy -- the moment right as the three gunshots sounded and it went a little harder and rhythmic.

Dark Shadows -- theremin!

opening few notes of Angel -- I always pleasantly anticipate that door coming off its hinges. I always liked this theme, from the first time I heard it. The use of cello/violin/viola/whatever that instrument is, is brilliant. I think it sets exactly the mood that the show is going for.

And yeah, "one banana two banana three banana four..." I have a t-shirt that says "One tequila two tequila three tequila floor" that always brings a smile to my face.
