In grad school, in the early days of the dotcom boom, some of us CS-ish people curious about startups would talk about them. One day, one of the PhD students asked everyone which dotcom's stock would they most like to have. I said Google. (It might not have been a company yet, but we kinda assumed.)

Google worked surprisingly well, obviously they were going to be hugely important (unless another player appeared and did a big next leap), and obviously they were smart. (On the side, I also got warm-fuzzies that the search hits I got seemed to have a strong Linux bias.)

The grad student who asked, coincidentally, ended up deciding not to finish his PhD, and went to Google. :)
