I would walk 500 miles

I'm a big fan of the series How I Met Your Mother, and I love the episode, where Ted and Marshall is driving Marshall's car and the tape is stuck.
Most of you have probably seen this before, and the tape with the song I would walk 500 miles is stuck and is the only song, that they can hear. I love it! Such a nice and happy song. Watch the scene here. The song is written by Kenny and the Scots.
