The new 118 118 ad makes me a bit sad, just because Ray Parker Jr looks so old. But I do love the 'I ain't afraid of no goats!' part.
My current hate (other than the Cadbury ad, and the Haribo detective one where the annoying little girl flips everyone off at the end) is the trend for moisturisers, etc. to use the phrase 'if you aren't ready for surgery'. It's like it's a given that everyone will get a facelift or botox, and if you're too wimpy, these eye creams are the next best thing.
