The Mighty Boosh (2004)

Following a somewhat poorly received gig, the boys decide to skip town for a bit. They take in a spot of fishing on Black Lake where, angry at Vince's fishing success, Howard sends him back to the local pub. Whilst Vince swaps tales with the locals at the King Prawn's Head, Howard is abducted by Old Gregg, the eerie merman who haunts the lake's waters.
