For comedy (though to be taken serious) was a BC Workmens Compensation ad showing all to "do-nots" on the job site; showing a guy with both arms going into a planner; another shot of a guy moving a ladder (having a plank throught it above) then the paint cans falling on hi heads, etc. My brother and I would die from laughing watchinh it.
For creativity, was one particular Chanel #5 ad shot in the early 1980's. Ridley Scott was still a fashion photographer at the time, then breaking in the video commercials. Its the one where the theme was to "share the fatasy" while the Ink Spots sang one of their many early hit. The one part of it where the shadow of the passenger airliner moving its way all the way up the John Hancock building in SanFran was the ultimate phalic shot ever on tv.
