Funny, one could say that theme song from our last road trip was the "So Here's My Number" song (no linky to protect those of weak constitutions), because of its meme-base connections and quotability.
We almost threw the annoying Siberian Husky out the left sliding door of my minivan because he just kept quoting it!
My sona's theme is these two songs synced with music and lyrics matching perfectly. I think it shows perfectly how my sona is a being of Twilight, the midpoint between Order (shown by the first song), and Chaos (shown by the second song).
My sonas theme will always be Hydro Phone because Pennington he lives near water and surfs.
