Dylan invented (pretended to be) a 'walking towel dispenser' (actually a walking 'roller towel', the kind that loops around when you tug on it, which used to be common in gas stations in America in the 1970s and is still common in England today - Dylan loves roller towels) by placing a large towel over his head and approaching people who might need to dry their hands. 'The walking roller towel walks toward you', he explained. People are encouraged to tug fresh towel from Dylan's back, over his head, and down his front.
