When he was in high school back in the 60s. Times have changed since then and every recent adaptation has him as a bit of a snarky smartass. The extremely timid nerd type that he was back then is extremely outdated now. Not to say they don't exist, but they aren't really seen as socially awkward anymore. Calling someone a geek back then was definitely an insult. Calling someone a geek now is more or less something to be proud of.
