Easy one
1) Big Baby because he's a baby and I could mold him into the son I never had.
2) Coddling him, changing diapers, gently rocking him when he's crying, holding him over my shoulder and burping him.
3) Pure bliss.
The thought of changing BBD's diaper is perhaps the scariest thing I've ever read on this blog.
I'd adopt Scal. He seems like a good guy, and I could have him shovel my walkway or something. Plus, it would keep him off the floor. 
And another plus, he won't just be limited to shoveling snow. He could answer phones, clean off your roof, dust your house. I mean sure, he might not be a top tier guy at any of those things, but that's the beauty of scal. While he might not be top tier, he rarely makes mistakes and he's 100 percent hustle.
But when he wads up the used paper towels and throws them in the trash, for gods sake stop cheering. It's such a jerk move.
