Nowadays TV adverts are woke signalling or just plain creepy; from the middle 90's here is the surrealism of Guinness's "Dancing Man".
This not only advertises the product unforgettably, achieving simultaneous artsy-ness and wit; but is very enjoyable even on first viewing.
PS: If you haven't yet seen The Best Advert Ever (i.e. Blackcurrant Tango): now is the time to treat yourself.
