This clip of Scrubs will go down as one of my personal favorites. You kind of have to see the whole episode to fully get it, or at least know a bit of the character's personalities. But either way, this is still amazing. Ha, so here it is. Enjoy. And you're welcome.
Ok so the lead singer's name is Turk. Here is his audition to be in the Cool Cats, earlier in the episode.
Again I say, you're welcome. : )
