ThinkGeek is selling men's and women's tee-shirts with the following geekarific love verse: "Roses are #FF0000 / Violets are #0000FF / All my base / Are belong to you." If there is a special geek in your life, s/he will find this adorable... and maybe even explain it to you. (via bsag—who chronicled an even geekier version of the poem last year—via Anja).
