I haven't got any favourites in particular, but the Safety Dance is good

The timing on this is just awesome, watch the whole way through.
Also, another favourite of mine (much more recent) is Fall Out Boy's 'What a Catch, Donnie', which is easily, in my opinion their best ever song (in fact, the band have also said that they feel it's their best song ever). By the way, can people please add links to the songs themselves when they post? Much appreciated
