Axe ad: Guy 1 in an elevator spraying himself with Axe deodorant. When Guy 2 leaves, Guy 2 enters, followed by a girl. The girl whiffs the deodorant, and is so turned on, that she jams the elevator to make out with him. Watch the ad here.
A rather unsettling variant of this ad happened to me. Replace 'deodorant-spraying man' (Guy 1) in the above ad with 'deadly-atomic-bomb-flatulence-spraying man'. Replace Guy 2 with me. And three girls entering the elevator instead of one.
