What happened: The "Spencer Hound" nickname followed Spencer Brown into Sunday, with the moniker replacing his surname in the latest round of the running joke. Brown had already played along this week, saying, "Those videos, I don't even know where it's going ... I guess I'm a dawg."

Why it matters: The nickname has lasted long enough to become part of Brown's regular chatter rather than a one-line bit. It also extends Brown's earlier 'Spencer Hound' turn, giving the joke another day of traction.

What to watch: Watch whether Brown keeps leaning into the nickname during the practice week. If it keeps resurfacing, "Spencer Hound" may stick beyond the joke stage.
