Jim and John Harbaugh share the family stories behind the famous "Harbaughisms"

Phrases like "Whose got it better than us" and "attack the day with an enthusiasm unknown to mankind" are now synonomous with the Harbaugh family.

Both John and Jim Harbaugh have embraced those two sayings, as well as a handful of others their father (Jack) loved to share with them, so much so that they've become a part of the program's and organizations that they've been entrusted to lead.

Each saying has taken on a life of its own over the years, and Jim and John recently sat down with each other to reflect on their first and most favorite memories of, what can only affectionately be called, "Harbaughisms."

Of note in the clip, the one entity that Jim believes embodies the phrase "attack each day with an enthusiasm unknown to mankind"?

In his eyes, that honor belongs to none other than Spongebob Squarepants.
