what do you think about penny and sheldon in big bang theory?

Wouldn't they make a good couple? They have a great on-screen
chemistry and honestly I think Leonard is just annoying now. I'd
rather have Sheldon be with someone who truly cares for him and has
the emotional side rather than someone like Amy(though she's
hilarious) or someone exactly like him. Penny already has opened a
certain side to him and in a way Sheldon/Leanard had made her look for
more intelligent guys. I absolutely love that she beat up a bully for
Sheldon; I used to think she was selfish or just indifferent to the
geeky stuff but I love her.

Also what'd you think of the 4th season finale?!?!
