C’mon, yunno ya wanna! Just write anything you want, as long as it follows the basic haiku format. Which is, if I’m not mistaken, a three lined poem broken up into a 5-7-5 syllable format. And, if I am wrong, then CRUD.
Examples:
The moose has two balls,
Not that it matters at all,
For he cannot lick!
Don’t fret little blonde,
A trophy wife you’ll soon make,
Wow, thank you, you say?
(These were submitted and allowed as suitable examples of poetry in my English class. Go figure.)

White peaks, such mountained distance.

I chose all the beer

Just a friendly reminder that true haiku are not simply poems with three lines of 5, 7, and 5 syllables. See the Wikipedia article on haiku.
