Annoyingly I cant find it to show you, but I love the current Egg tv ad with the Guinea Pigs.
The first ads were great, and on this one they try to find out their opinions so put in robots with furry wigs on. Its amusing, and its also a very well produced world within the ad; down to little details like the clothing and the places they go.
One of my favourite bits is the art gallery where (for example) the terms and apr details are written as if on a piece of art by Barbara Kruger (and they have her style exactly right).
Its a nice ad, but it has such good attention to detail, which elevates it higher in my view.
