Firefox t-shirts

I was a little worried about seeing this t-shirt on the Firefox website this morning. Does wearing it make your head, arms and legs disappear? I presume that the label has the following printed on it:

<style type="text/css">
head, arms, legs {
display: none;

p.s. that’s a geek joke!
