In honor of our great appreciation for those who love to order, classify, categorize, group, arrange, grade and rank (and just in time for Taxonomist Appreciation Day), Buzz Hoot Roar is proud to announce its fourth annual pun contest.

Check out one of last year’s winners:

Pun by Emily Dangremond, @Docta_Danger. Illustration by Buzz, @verdantrobin.

Here’s how it works:

1. Tweet us your best taxonomy-related pun by Friday, March 10.

2. Our celebrity judges will select five favorites.

3. Winners will receive: their puns illustrated on Buzz Hoot Roar’s blog, a set of printed greeting cards to share with the taxonomists in their lives, and a BHR super-soft T-shirt.

Let the witticisms begin!
