Hmm... there are too many to choose from!! There should be hit charts for this too :D However DJ Bobo's "Chihuahua" tops the list I think. Not that the lyrics matter that much though... half the hits at any one moment are always remembered for how catchy they are, not for the sense of the words they contain! Can't you remember yourself jumping around to Las Ketchup's 'Asereje' last summer?
