Greg and Joshua are back! And this time, Greg's pool is open, so of course the boys are goin' for a swim. They can't resist the opportunity to goof around at the bottom of the deep end - dancing is a lot more challenging when you're under nine feet of water, but it doesn't stop them.
As for underwater dancing, Felicity has done it before and while she agrees it feels nice, like you said, it's slow and bulky as hell.
