I love the 'all i want is you' video by u2, in fact I loved this video ages back when I was little and still if I see it today I still feel strongly about it.
It features the dwarf who has fallen in love with the trapeeze lady in the circus and I think she is in love with him too but has an other half.
I think I have a crush on the dwarf in it too, he is quite hot.
Other videos I like are four tet, 'smile upon the face', it almost put's a positive spin on a sad subject and I think it suits the music and the song title perfectly.
And also, I think daft punk's video for 'digital love' is awesome too.
