Future Ted: [v.o.] So Marshall walked in the next morning all ready to quit. But then something weird happened. Suddenly, he didn't hate the paperwork. He didn't hate the coffee. He didn't even hate the dirty jokes. Out of nowhere, Marshall actually liked GNB.
Robin: It's graduation goggles.
Marshall: What?
Robin: Graduation goggles, like with high school. It's four years of bullies making fun of all the kids with braces, even after the braces come off and they can walk just fine. But then, on graduation day, you suddenly get all misty because you realize you're never going to see those jerks again.
