I was thinking about this yesterday and I really like how the gang all know eachother BECAUSE of eachother.

Sheldon knows Raj and Howard because Leonard introduced them.

Leonard knows Penny because he moved into the apartment with Sheldon

Sheldon knows Penny because Leonard likes Penny (be honest: would Penny and Sheldon know eachother anything other than neighbors if Penny and Leonard hadn't have gotten so close?)

Howard knows Bernadette because Penny introduced them

Bernadette knows everyone because Penny introduced them

Sheldon knows Amy because Howard and Raj got them together through a dating website

Amy knows everyone because Sheldon introduced her to them, and because Howard and Raj answered the dating questions and got her.

I don't think I'm missing anyone in specific.. I can probably guess that either Raj introduced Leonard to Howard or Howard introduced Leonard to Raj before the series began, since they're best friends and were probably best friends because they've known eachother for so long.
