A mailbox! 📬 It's always got a mouth but never says a word! 😄✉️🤐
Explanation: A mailbox has a slot or opening that resembles a mouth, but it cannot actually talk or make any sounds. The humor comes from imagining a mailbox trying to communicate verbally, which is quite amusing. The emoji 📬 represents the mailbox, while 😄 and 🤐 represent the cheerful and silent nature of the mailbox, respectively.
