We wrote targeted ads to really get into people’s heads and colds.
Ads on public transport meaning you have nothing else but to read them so why don’t we make it extra long.
Beechams wanted to run their US campaign in the UK, but instead we convinced them to go for a campaign with a British tone, reminding people that even though you don’t feel your best when you have a cold, you can still try your goodest.
(Or "Do your best", which is how others might put it.)
