The story is not complicated. Three men decide to go hunting whales. (A perfectly reasonable thing to do in Northrend, mind you, as the whales there aggro from about a hundred miles away.) Despite their better judgement, the three men are convinced to let a gnome go with them. This proves to be a complete and total disaster, as gnomes are, apparently, filled with curses and spite. They all die.
Gnome Overboard is the resurgence of another favorite aspect of Oxhorn Brand Machinima. His music is creative, fun, and interesting. While I admit the voice in this song seemed to struggle a bit, his lyrics were amusing and cleverly written. On that subject, Oxhorn has also made his music available for purchase on Amazon.com, so if you like his work, you can pick it up fairly easily.
