Say what you will about ads, but you have to admit that when they're done well they're not only entertaining, but they also manage to stick in your brain for decades.
With that in mind, we started thinking about all the classic chocolate ads that aired over the years and did a bit of rooting to find the most memorable.
Time for a trip down memory lane...
1. The Crunchie rollercoaster
People made of chocolate riding a rollercoaster that launches them into outer space? Yup, that is what Friday feels like.
2. Snickers' 'I'm Batman'
The ad that launched a thousand impressions in primary schools around the country.
3. Cadbury's gorilla
Ape + a drum set + Phil Collins = advertisement gold.
4. Cadbury's kids with crazy eyebrows
We dare you to watch this without arching an eyebrow. Can't be done.
5. Cadbury's Caramel Bunny
The sexualisation of cartoon rabbits really needs to stop.
6. Ferrero Rocher ambassador
This is the reason you still manage to feel fancy when gorging yourself on Ferrero Rocher.
7. Mars Delight
This just looks ridiculously tempting.
8. Flake in a bathtub
9. Creepy Kinder Egg ad
This is memorable as it will haunt your nightmares for the rest of your life.
10. Thank you very, very much, Roses
We still get this tune stuck in our heads whenever someone mentions Roses.
