Bill Gates and Paul Allen hacked their school's computer to help Gates meet girls
Although Allen was two years ahead of Gates in school, they became friends over a shared love of computers.
One of the things they used to do was to hack into computers.
They even came up with a scheme to hack computers to help Gates meet girls: they enrolled him into classes where he was the only boy, he confessed in an interview with BBC.
Unfortunately, that didn't really help him, he told BBC's Kirsty Young (emphasis ours):"Paul did the computer scheduling with me. Unfortunately for him he was two years ahead of me and he was off to college by then. So I was the one who benefited by being able to have the nice girls at least sit near me. It wasn't that I could talk to them or anything - but they were there. I think I was particularly inept at talking to girls, or thinking, 'OK - do you ask them out, do you not?' When I went off to Harvard I was a little bit more sociable. But I was below average on talking to girls."
