Since the Nobel Prize in Physiology or Medicine was awarded to Martin Evans, Mario Capecchi, and Oliver Smithies for developing knockout mice — creatures that lack individual genes — this year should be remembered as the year of the knockout mouse.
To celebrate, we invite our readers to caption mouse pictures with phrases related to genetics.

While you can submit as many mice as you want, you can only submit one every 30 minutes. No HTML allowed. Please be sure that the images are no more than 500px wide.
