any good animé dances?

going to an animé convention in september and since i didnt sing karaoke at the last one. my Friends are forcing me to sing. so im thinking if im gonna sing i might as well do dance with it to make it plus interesting. not gd with ad libbing, so im just going copy some animé song. the only animé songs that i know ou remember that have a dance is the lucky étoile, star one and the haruhi one. any other suggestions? thanks
