I've got scroll buttons like the day is long
As a frequent visitor to http://www.homestarrunner.com , I've heard the song that Strongbad sings about his scroll buttons many times, and I have it stuck in my head. I wanted to find out where the phrase "Like The Day Is Long" originated from, because I know I've heard it before, but never really thought about what it means. I assume it just means "a lot".
But I've been singing the song around my colleague who's Japanese, and is confused by most expressions I use. I tried to explain what it meant, but don't think I succeeded. I did a Google search for "like the day is long", but wouldn't you know it, all the results where about someone having scroll buttons like the day is long.
Really? Please tell us more.
