What is a three lined poem with 17 syllables?

A haiku is a three line poem that follows this pattern: the first line is five syllables, the second line is seven syllables, and the third line is five syllables, for a total of seventeen syllables. "Each Haiku must contain a kigo, a season Word, which indicate in which season the Haiku is set. For example, cherry blossoms indicate spring, snow indicate winter, and mosquitoes indicate summer, but the season Word isn't always that obvious."
