My 2 favorite Frank Tripp lines.
From season 4's Felony Flight:
Frank(to Eric): Hope you're not allergic to dust.
From the episode that aired earlier this week-Burned:
Frank(to Horatio): First, it was a damn land mine. Now a flying water heater. What next?
Horatio's response: Next, we catch a killer.
*cut to annoying, loud, screeching, off-key, sounds-like-an-elephant-stepped-on-his-foot YEAH in the theme song*
[edit]
OOPS!!! Forgot something.
Frank and Horatio each have a good line in a scene in JUST MURDERED. Here are those 2 good lines...
Frank: I'll get a radio car.
Horatio: Frank, get 2 cars.
