2. Ross Geller.
Ross is still at New York University, in spite of being widely known as one of the worst professors there. He has dated several of his students and each time has manipulated them into not telling the university administration about their relationship by saying that if he gets fired, he won’t be able to pay child support and his children will starve. Because of this, no formal complaints have ever been made against him, although he does have a reputation on campus as a whiny womanizer. Female first year students are often warned not to go to his office after hours unless they want to be coerced into pity makeouts.
In 2012, Ross published a book called The Science Behind Jurassic Park, which spent a remarkable twelve weeks on the New York Times bestseller list. He and Neil deGrasse Tyson began a friendship on twitter, which then progressed to email and finally meeting in person. Phoebe recently bumped into Ross and Neil while they were out for coffee together, and although Ross was dismissive and condescending to Phoebe, Neil was completely charmed by her. Ross doesn’t know that Phoebe and Neil have met twice since then for herbal tea.
When the Red Wedding episode of Game of Thrones aired, Ross posted a lengthy Facebook status shaming people who hadn’t read the book before watching the show (and gleefully pointing out every discrepancy between the two).
Ross worries on a daily basis that George R.R. Martin will die before finishing his next book.
