UH... Chewbaccas...I guess...
These are just weird.
For those romantically inclined individuals, Mathew has created this mashup of Cupid and Chewbacca: Chewpid! If you have not yet gotten your significant other a Valentine's card yet, there is a printable version you can access by clicking Chewpid. Just save the image it takes you to and print it out on an 8.5 X 11 sheet of card stock or regular paper.
