The 'Number Rhymes' memory system

This system is mainly used for double digits but can be used for single digits.

The idea is that a different catchy rhyme can be applied to numbers, along with a cultural or visual link, to aid memory.

The idea comes from the 'bingo calls' used in British bingo calls. However these suffer from a number of problems:

- They only go up to 90
- Often the rhymes are arbitrary, with no other link
- Sometimes they are based on a cultural or visual link, but there is no rhyme

As such we present a list of the numbers 0 to 99 that we think provide better memory hooks, using the rhyme method.
Note, in a small number of cases there were either no good rhymes or no good cultural or visual references, but we have kept these to an absolute minimum, for example:

37 - "Body temperature"   ( This is the body's normal temperature )
27 - "Duck and crutch"   ( This is a standard bingo call. The idea is the 2 looks like a duck and the 7 a crutch.
