Leonard: Sheldon, relax.
Sheldon: How can I relax? My nervous system is being stretched out like the strings of a harp and plucked by holes, and birds, and wind, and the low-hanging scrotum of the difficult-to-evict Professor Rothman.
Leonard: If you're not happy, why don't you just let Kripke have the office?
Sheldon: What, and let him win? Do I look crazy to you?
