Sweat patches may not be attractive, but in a TV ad for Lynx Dry they help a master fisherman catch fish. He sweats so much he attracts fish under his armpits until he discovers the deodorant and loses his attraction to his finned friends but gets the girl. The Unilever ad, which was first aired briefly last year, will appear on screens from this week until September as part of a £2m spend on Lynx in 2009.
