The phrase "how do we tell him?" comes from a meme originating from the SpongeBob SquarePants episode "Dying for Pie" (Season 2, Episode 24A). In the episode, Squidward accidentally gives SpongeBob a pie filled with a bomb, and later, Squidward and Mr. Krabs are worried about how to tell SpongeBob that the pie is dangerous. The phrase is used online as a humorous way to depict situations where someone is naive or unaware of an unpleasant truth, and others are unsure how to break the news to them.

If the question "how do we tell him?" refers to how to tell someone difficult or sensitive information, it depends on the context and nature of the information. Typically, it involves being gentle, honest, and considerate, choosing the right time and place, and preparing the person emotionally for the news. The phrase's meme origin captures that hesitation and concern for delivering bad or alarming news.
