Daily Dose of Awesome: Happy Days theme song

I never really got into Happy Days.  Admittedly, I've only seen a handful of episodes, but the show's style of humor never grabbed me.  However, I love the theme song.  There are actually quite a few shows where this holds true for me Matlock and Perry Mason being more dramatic examples.

But I digress, this song is pure happiness.  I guess it's not surprising given that the word "happy" is in the title, but I thought it was worth mentioning never the less.
