antena man serenata

No explanation what so ever, so we tried to work toughly on AUTOCAD, while this man behind with a strange antena on his head came and evoked a bob dylan song, it lasted like 30 minutes, but we really had strange vibes during our concentration, maybe the antena, maybe his singing, but after this serenata (not on tape) we put a chop suey taco in his mouth and he miracously shutted up.
