Short Answer: 🕰️ The cafeteria clock was always behind because it was on a perpetual lunch break! 🍔😄
Explanation: The humorous explanation behind the cafeteria clock always being behind is that it simply couldn't keep up with the fast-paced lunchtime demands. Just like how we sometimes feel like time slows down during lunch breaks, the clock decided to take a permanent break too! Its love for food and relaxation got the best of it, making it perpetually lag behind the actual time. 🕰️😋
