Tony likes to call them the B Brothers because their names are Billy and Baa-b.
They kind of remind me of the Odd Couple or something. They have a rather unlikely friendship.

Yet day after day, they seem to grow to love each other even more.
Baab seems to keep a little extra spunk in Billy's step while
Billy keeps a watchful eye over Baab.

Watching them both just makes me happy.

Nice, isn't it?
