Fig. in a very short time; very quickly. Jane returned in two shakes of a lamb's tail. Mike was able to solve the problem in two shakes of a lamb's tail.

Also, in a jiffy or second or trice . Quickly, immediately. For example, I'll be with you in a flash, or He said he'd be done in a jiffy, or I'll be off the phone in a second, or I felt a drop or two, and in a trice there was a downpour. The first idiom alludes to a flash of lightning and dates from about 1800. The word jiffy, meaning "a short time," is of uncertain origin and dates from the late 1700s (as does the idiom using it); a second, literally one-sixtieth of a minute, has been used vaguely to mean "a very short time" since the early 1800s; and trice originally meant "a single pull at something" and has been used figuratively since the 1500s.

Instantly, very quickly. Lambs surely were known to be frisky creatures long before, but this expression, often shortened to in two shakes, dates only from the early nineteenth century and originated in America. Mark Twain changed it in The Adventures of Huckleberry Finn (1884) to “three shakes of a sheep’s tail,” suggesting it was already very well known by the late nineteenth century. A similar cliché, in a trice, which came from a now obsolete word meaning to pull on a rope and alluded to a single pull, is rarely heard today but was extremely common from the eighteenth century on.
