Cough syrup

A yellow-skinned man holds a bottle of Krusty's Non-Narkotik Kough Syrup, then pours the purple liquid into a blender, blends it, and drinks the resulting purple liquid, which causes him to have a dazed expression as a statue of David appears beside him blowing a pink bubblegum bubble. The scene takes place in a kitchen with a purple countertop and a television screen displaying a distorted image of the man and the statue.
