If being a Celtics Dancer has always been your dream, you'll have to wait until next year to achieve it. The franchise picked its new girls last night at the Roxy, selecting 17 dancers out of 39 finalists (who had been whittled down from 200 initial candidates). The Globe and the Celtics Dancers both have photo galleries for those who want to learn some moves--or, more likely, get some fashion ideas--for next year. We kind of wish the Celtics Dancers had a better team name--like, the Leprechaun(ette?)s, Pots of Gold, or Lucky Charms. Do you have any brilliant name ideas for these lovely ladies?
