Chief and Rockapella in “Unfinished Business”

This is Top Grunge.

(singing) Top Grunge

Crossing over that traffic divider, he was an extra in Easy Rider. His last known whereabouts: Mount Washington, New Hampshire. Don't you just love the view from atop a tall mountain? Don't you really love when you don't have to hike to get there? Well, if you want to look out from atop Mount Washington, the famous Cog Railway is one way to go. Steam, created by burning coal, provides the power to turn a large gear called a cogwheel. Teeth on the gear hook into the track, moving the coach car up and down the mountain. For over a century, the Cog Railway has chugged folks 6,288 feet to Mount Washington Summit to enjoy the view. Or it did until today...

(singing) Ooh!

...when New Hampshire's niceness was nastied by Top Grunge. He chased the train off the tracks, hopped into the coal car, naturally, and commandeered the Cog right off the rails. Gumshoes, get us back on track and solve today's case...

(singing) Woo-woo-oo-oo

...I'VE BEEN BURPIN' ON THE RAILROAD!
