End Credits Song: (Sung by Queeks)
People make me crazy, but I've found a personal cure.
Some say I'm lazy, but I'm not so sure.
I sleep. I've had a long and tiring day. Just leave me alone.
Get out of my life. I'm trying to sleep.
Whatever you want, I'm sure it will keep.
I sleep. Don't you people have anything better to do than look at an old man sleeping?! Go away!
The title The Three Amigas is a take on the movie comedy Three Amigos, which starred Steve Martin, Chevy Chase, and Martin Short as unemployed actors who think they're making a comeback when they're hired by a Mexican village to fight bandits. Only this is no story as the threat is real and the actors have to improvise, leading to comedy hijinks.
The title of the second short is take on the story Sleeping Beauty.
