As a kid, I usually got Brut and Hai Karate mixed up when they were being applied - way too bright for anything I'd personally wear, but my father loved Hai Karate and Brut, with the latter actually calming down to something that was a scent that I remember fondly... Hai Karate not so much.

To me, they smelled the same initially. But those commercials... heh. Low-brow yet intensely funny.
