Sibling humor

My my kids love listening to podcasts and enjoy humorous writings or acts. They love to exchange ideas. This morning, they found one particular podcast at the same time , independent of each other. The podcast was humorous enough that they wanted to share immediately. In a comic way, they dashed out of their rooms at the same time ande ran into each other in the hallway, each was eager to show the other what was on their phone. It was the same podcast and poused at the same spot. Laughter erupted. I had no clue what it was or why it was so humorous. Their laughter was proof enough.
