After a bad gig, Howard and Vince travel to a village in Scotland called Black Lake to take a break. At the pub, they get the idea of going fishing; which Vince seems instantly proficient in. Vince soon leaves a disgruntled Howard to fish himself. Vince returns to the pub, where he learns about Old Gregg. Howard then inadvertently catches Old Gregg, who shows him his mangina, and takes him to his underwater cave. Vince phones Naboo to help him rescue Howard, which Naboo grudgingly agrees to do. Howard awakens, and has a short conversation with Old Gregg, ending in them performing a song together. While having a meal with Old Gregg, Howard learns of his possession of The Funk. While Old Gregg is preoccupied, Vince, Naboo and Bollo arrive in a submarine, and rescue Howard, who steals The Funk from Old Gregg. They use it to perform to the pub, singing a song about having the funk. They then leave, planning to bring the funk back to London. Old Gregg is shown to be riding atop their van; exposing his mangina. (thetvdb.com)
