Jim and Mayim's chemistry.

Is it just just me or does it seem like they’re really close? From the interviews or bloopers and so forth I’ve seen them in together it seems like they really enjoy each others company. Or is it just me who thinks this? One of my favorite exchanges between them is when they’re interviewing each other and Jim says something along the lines of “yeah I’m rooting for us (sheldon and amy) too!” And then Mayim says something like “really? Well I can tell them to turn the cameras off right now ;) …” Idk even though I know they’re just kidding I find the exchanges between them are charming and cute and make me happy that they get along well.
