The end of the rainbow

Lousy day today so a pot of gold (well, low to medium denomination coinage) at the end of an indoor rainbow.

Could never get the hang of that Richard Of York mnemonic but my physics teacher taught us:
Read
Over
Your
Geography
Before
I
Vomit

It's stuck for over 40 years so it must be pretty good, sort of thing to appeal to teen-age boys!
