I think this poem might be familiar to many(it is one of those cult-following things, I hear). Worth memorizing.

Razors pain you; Rivers are damp;
Acids stain you; And drugs cause cramp.
Guns aren't lawful; Nooses give;
Gas smells awful; You might as well live.

- Résumé, Dorothy Parker.

I'm famously not good at explaining poetry, but this is a no-brainer :). What gets me is the light-hearted rhyming scheme, and the undertone of pain. YMMV. 

Update: Dorothy Parker was well known for her wit, apparently. The Wikiquote page has many a gem (might offend some). One:

"Pearls before swine."

(When she and Clare Boothe Luce were entering a room, Clare hung back, saying, "Age before beauty"; Dorothy swept into the room with this retort)

(This is #150 on the minstrels collection, and no, I don't know why I have turned to posting poems now. I'm sure the phase won't last.)

PS: Okay, the fact is, I had to move most of the data on my computer to another hard disk to make space for something else, which means most of my photos are now 'away'. AND I have been swamped with things, so no time to sort/sift through existing stuff.
