We were blown away by the death-defying roller skating act that siblings Billy & Emily England performed on their first appearance on 'America's Got Talent'.
We're even more amazed by their latest routine. We think this is one of the best acts on AGT this season, although we worry about how they might try to up their game even more, when the live episodes begin in a few weeks.
Needless to say, don't try this at home boys and girls!
