Totally agree, and in fact, when Penny said "I love you, but you drive me crazy!" I though Leonard was going to say "well, if I drive you that crazy, maybe we shouldn't be together", but then the keyed on the "I love you" part instead. I would much rather see Leonard with Sheldon's assistant. She's damn cute (and smart, too!). But then once again, poor Raj gets left with no girl.
