pull a fast one
idiom

- to successfully deceive someone

(American Heritage Dictionary)

---
Although the origin of the expression "pull a fast one" is not known, we can take an educated guess as to where it came from. A "fast one" has long been slang for a trick or deceit and likely stems from so-called sleight-of-hand games, such as those that use playing cards or dice, in which the trickster relies on speed to fool the customer. Pull, as used in this phrase, is simply a synonym for doing or accomplishing something. A similar phrase is "pull the wool over someone's eyes."

Speaking of pull, this is an extremely popular word found in a wide range of phrasal verbs such as "pull ahead" (to move in front, as in a race) and "pull off" (to accomplish something despite difficulties), in addition to being applied in idioms like:

- pull oneself together = to regain a stable mental state (He pulled himself together after the boss yelled at him for being late)

- pull out all the stops = to use every resource that one has (She pulled out all the stops to complete the project on time)

- pull the plug on something or someone = to stop supporting or bring to an end (Management pulled the plug on free coffee in the office)
