Funnily enough, I was looking up one of my favourite old adverts on youtube last night, the Tennants Pilsner one where it's filmed in reverse. Well known for the 'Czechoslovakian yeast!' bit.
There was a Bonjela advert ages ago where a couple got married or something and as they kiss he hurts his ulcer and turns to the camera and gurns - used to crack me up for some reason but apparently it never existed.
Remember this first being shown during the half time of an everton televised game in the 80's when I was a kid, never seen an advert like it before and loved it
