Cliché: in two shakes of a lamb's tail

Meaning: very quickly. Further on meaning.
Rewrite 1: in two heartbeats
Rewrite 2: quicker than you can shake a lamb’s tail
Rewrite 3: quicker than you can say, “lamb’s tail”
Rewrite 4: faster than you can say, “Get it.”

Comment: This one was a little harder that I thought it would be to rewrite. Perhaps because you want it to be short but some things need more language to explain or set up the comparison.
