Episode Summary

Sheldon, in an attempt to access a coveted computer, tries to befriend the unsociable Kripke. He creates a complex "friendship algorithm," inspired by a children's book. His efforts include distributing questionnaires to understand why people like him and an awkward attempt at making friends in a bookstore. Sheldon and Kripke's rock climbing outing ends with Sheldon panicking at the height. Ultimately, Sheldon learns his endeavor is pointless as Kripke can't grant computer access, but he's admired for his persistence.
