It just finished on E4 and I completely agree with #4, #3 and #1.
4 was the electricity one when they spoke to random people on the streets and used their voices and used them with cartoons as they made the ad look as boringa s possible, but with funny stuff going on in the background (the birds) and the sneeze the penguin does and the glasses fall off
3 was the Tango Happyslapping Advert, that was insane how popular that got that people actually did it to each other. In primary school (1996 onwards) people were doing that to me, and i was doing it back.
1 was the Guiness Surfer Horses Ad, absoloutley love that ad, soo epic and the horses over the waves are soo cool.
Other ads I love are:
Levi's Twisted Ads, thought they were amazing, the music choice for that was awesome.
The one with the paint exploding over the flat (from about 2 years ago)
