Bart Simpson stands in a classroom before a chalkboard filled with rows of the chalked line "I WILL NOT BARF UNLESS I'M SICK"

What happens

Bart Simpson, the boy with spiky hair in an orange shirt and blue shorts, stands in a classroom before a chalkboard filled with rows of the chalked line "I WILL NOT BARF UNLESS I'M SICK." He first stands with one hand raised to his mouth and his body turned toward the board, then he hops sideways to the left with his arms outstretched and a wide grin, eyes squeezed shut. A red trash can, a wall clock, and a framed picture sit on the green wall behind him. Before these classroom scenes, the sky of clouds on blue fades in and the title card "THE SIMPSONS" appears in yellow letters over the clouds.
