Day and Night (0:06) 2010

I believe Day and Night was shown with ToyStory3 because this was not new to me. The two characters, Day and Night avoid each other like the plague. Slowly, they come to realize that each has its own advantages, Night sees Day's girls sunning themselves at the beach and Day sees the colorful Las Vegas night life. Over time, their relationship grows into a friendship that is mutually beneficial. This animation is very clever.
