I don't know Haiku?

 I am supposed to write some Haiku's for my creative arts class.  I have not been given any instruction on how to do it or what rules are involved.  The only instruction I have so far is that it is a short poem of 17 syllables distributed over three lines –five, seven, five.  Given this instruction, here are my first attempts.

1)      Speak to audience

Mouth is dry and tongue is thick

Picture them naked

2)      Slice juicy lemon

Liquid splashes in my face

Scream, tears, blurry eyes

3)      Splash, plop, frog in flight

From below a large fish gulp

Last swim of the day

4)      Clouds drifting fluffy

Darkened sight obscures the path

Fall in hole unseen

5)      Ragged breath, wheeze, cough

Hoisted box, stumbled up stairs

Wife complains, wrong box

6)      Shirt and pants too tight

The scale mocks my swollen gut

Tears, a salad night
