Don't Forget Your Rubbers

I'm not the most happy with this one.  In fact when I was making it, I was on Skype (or IRC? Actually don't recall which) and mentioned how I was having difficulty drawing the image, and how ugly it was turning out.  But oh well.
The shirt is meant to have a rubber ducky on it, with the phrase "Don't Forget Your Rubbers" (or 'the rubbers', I don't remember.)
