Number four will be fascinating. Will it be ROY G. BIV for the rainbow, or “Bad Boys Rape Our Young Girls But Violet Gives Willingly” for the color bands on a resistor, or perhaps “Every Good Boy Does Fine” for the lines on a musical staff? Do they still teach “HOMES” for the Great Lakes in school? How many are there that I’ve never heard of? I await anxiously.
HAR! Good one! I tip my hat to you Sir!
Except mine cause I went with doormat thinkin’ it’d be the popular answer. Actually my spare key is hidden in a fake rock. However, it’s in a fake rock garden so it’d take a while to find it. 
I thought “The dog ate it” would be popular, but not THAT popular!!
Sorry, Dolores, I misread your explanation for how to list the mnemonic device one. (That’s what I get for posting when my pupils are still dilated!) I’ll repost mine:
- Button
- 75
- Briefcase
- Planets in the solar system
- Milk
- Pass
- My computer crashed
- Smell
- In a fake rock
- Phone numbers
“The conch ate my homework!”
Hehe. I had that answer, then changed it because I figured, I’d go with a realistic, tech-savvy answer. Nah, simple is always best.
ETA: Sigmagirl, yes, there is love for the fake rock!
