As a Copywriter, I like to look for creativity everywhere - not just in ads. And some of the best and most impactful instances are in the last places you would least expect to find it.

E.g.
" Funny 404 pages
" Creative/disarming entry forms and data capture mechanisms
" Cinemagraphs in place of Team photos on an agency website
" Product packaging - e.g. On the bottom of Innocent smoothie cartons, there's a single line of copy that says 'Stop looking at my bottom'
" Online dating profiles - mine is written in the style of an Amazon product listing
" And whatever else I can find… :)
