Swish cheese.
Explanation: This joke is a play on words involving “Swiss cheese,” a type of cheese known for its holes. The humor lies in the word “swish,” which refers to the sound made when a basketball goes through the hoop without touching the rim or backboard, creating a perfect shot. By combining “Swiss” with “swish,” the joke connects the world of basketball with a common dairy product, resulting in a lighthearted pun.
