Ron Swanson truly prefers his Scotch neat.

Ann Perkins:

“Ron, you’ve been sweating in here all day. Are you drinking any fluids?”

Ron Swanson:

“Yes. Plenty”

(he pours himself a glass of Scotch)

Ann Perkins:

“No, you need to drink water.”

Ron Swanson:

“Usually I take it neat, but I will make an exception in the name of health.”

(he takes one ice cube and drops it into the Scotch)
