Hahaha, I saw someone in the hallway wearing a contractor badge and a MIT hoodies. I am an alum so I asked about their time there. They said they graduated in 2003 but started in 91. I said, "Woah that's one helluva of a PHD." Turns out, they took a 10 year gap to play blackjack. Now they just work for fun every couple of years because they otherwise get bored.
