We see slow-motion pictures of plumbers’ butt cracks. The camera shows them crouched, working, and in those positions, we see parts of their backsides and underpants. The images are so unpleasant they are funny:Hairy backs and asses;Heart-print boxer shorts;A plumber scratching his butt;Old and frayed underpants;A plumber wearing thongs;A plumber who shaves his ass, etc.Those scenes are shown to a beautiful waltz, giving them all an air of lightness.Lettering:Leaks bring more headaches than you imagine.Use Tigre. High quality hydraulic systems.
