It's Opposite Day on Sesame Street! Everyone's celebrating by doing things that are as different as they can be. Alan whispers quietly and shouts very loudly while Elmo runs very fast and very slow. Slimey opens and closes the lid of Oscar's can and Grover stands near and far. Bert and Ernie notice they like opposite things like the stripes on their shirts, talking loudly or whispering, and having a messy or clean apartment. They may be different and do the opposite, and they're still friends.
