I love the MST3K and the Hans Solo/Chewbacca stars ones! Very cool! :-)
The MST3K is hands-down my favorite, followed closely by the "You Just Got Passed by a Toaster" (former Cube owner here!), and rounding out the rear (heh heh) is "Beer Guzzling Baby Daddy and his ho." HAHAHA!
That cat one frightens me. Someone actually thought that was a good idea.
