Oh, and the meme…

In a black-and-white animated scene, a large cannon fires a shell from a trench, sending a fish flying through the air. The shell lands in a wooden chest, causing a character to jump in surprise, while another character in a military uniform reacts with alarm. The sequence ends with a character in a submarine-like interior, holding a device and looking distressed. The setting is a war-torn trench with sandbags and a sign reading "Gulf of Mexico."
