The first 4-leaf clover of my lawn was a 5-leaf clover

Written on the outside of a geico-wants-your-business envelope

IMPORTANT:
Do not deliver to the wrong addressee
Do not bend, fold, spindle or mutilate
Do not lock your keys in your car
Do not wear brown shoes with a navy suit
Do not forget your mom's birthday
And Do Not pay too much for car insurance!

In some lab protocol manuals:
Floptical Diskette-> It sounds like the long version of floppy disk.
(the short version is flosdk!)

Acceptable water-> "Add 5ul acceptable water."
(a little bit subjective for a science protocol, don't you think?)

Open the top of reagent bottle 4. If the reagent pack does not have bottle 4, skip this step.
(for those people who would have spent an hour trying to open a nonexistent bottle)


Recently I realized there is a group of three songs that I always cross-reference and have trouble separating into three entities; I think of them as the same song.
They are:
Under the Bridge by Red Hot Chili Peppers
Freefalling by Tom Petty
Lightning Crashes by Live

I mean all three have a similar sound, and they're all about the same things. Angels and vampires and walking in the city and the city being your friend and angels and cities... Right?
