This carries over from the "Lasagna" episode of Aqua Unit Patrol Squad 1 where Carl is imprisoned under house arrest and made to wear a collar that electrocutes him when he crosses over the electric fence. The cops and Hand Banana's father, Master Shake enjoy tormenting Carl as can be seen in this image: [link]
I was wondering if after that electric fence was removed if Carl became trained the way dogs become with the same setup. I'm amused by Carl's own doggishness, and Hand Banana's lack thereof. So that's what inspired this little comic, that and the idea of love leading to mental freedom from captivity and enslavement... but anyway.
Carl Brutananadilewski and Hand Banana are characters from Aqua Teen Hunger Force/Aqua Unit Patrol Squad 1 on the Adult Swim network.
