I'd be willing to dance. Heck, I already have done performed the Haruhi dance to some degree in public, usually as I'm walking along while singing Hare Hare Yukai to myself.
Sadly, my friends, even though they've seen the anime already, still give me weird looks 8D;;;
Ooh, we're talking about Suzumiya Haruhi no Yuuutsu now? As everyone has already said, the dance is awesome. I love it, it would be cool to learn it, but I don't like dancing. I have however, learned part of the song. I used to know more, but I forgot a lot of it. D:
I would try and learn it, but I need more people to learn it with me or it doesn't work. D;
I'm the only one I know personally who knows it. I might force my brother to learn it, though.
None of my friends will. :(
I've shown my friends the show. D: They're either uninterested or they flat out refuse to do the dance. ;_;' But it's a lot of fun, so I'm not sure why.
You can always try bribes.
"DANCE WITH ME AND I'LL GIVE YOU GOLD." =D
