Once I went to the cinema and with the pre-film trailers there was this short film that showed a orchestra of human voices providing vocal sound effects for a Volkswagen, a bunch of grown adults making stupid car noises with nothing but their vocal chords, "Brrummmmmm" "Zozzzshhh" and it went on for, I'm not joking, 15 MINUTES! One of the wankiest things I've ever seen.
