like ice under a Zamboni... (35.50)

Ira: It's just a transaction to you, this whole thing? Numbers move from here to there, and emotions are smoothed out, like ice under a Zamboni.

An ice resurfacer is a vehicle or hand-pushed device used to clean and smooth the surface of a sheet of ice, usually in an ice rink. The first ice resurfacer was pioneered and developed in 1949 in the city of Paramount, California by American inventor and engineer Frank Zamboni. As such, an ice resurfacer is often referred to as a "Zamboni" regardless of brand or manufacturer.
