I could argue that Marge and Homer Simpson went to my high school. One of the artists back in the early days of the show attended my high school, so he drew Springfield High School like mine.
I always thought she must be fictional 
Another Rensselaer Polytechnic Institute “Tute” grad here. Others covered the fictional. Here’s the boring nerd graduates.
Many RPI graduates have made important inventions, including Allen B. DuMont ('24),[140] creator of the first commercial television and radar; Keith D. Millis ('38),[141] inventor of ductile iron; Ted Hoff ('58),[142] father of the microprocessor; Raymond Tomlinson ('63),[143] often credited with the invention of e-mail; inventor of the digital camera Steven Sasson[144] and Curtis Priem ('82), designer of the first graphics processor for the PC, and co-founder of NVIDIA. RPI Prof. Matthew Hunter invented a process to refine titanium in 1910. H. Joseph Gerber pioneered computer-automated manufacturing systems for industry.
In addition to NVIDIA, RPI graduates have also gone on to found or co-found major companies such as John Wiley and Sons, Texas Instruments, Fairchild Semiconductor, PSINet, MapInfo, Adelphia Communications, Level 3 Communications, Garmin, Bugle Boy and Vacasa. Several RPI graduates have played a part in the U.S. space program: George Low (B.Eng. 1948, M.S. 1950) was manager of the Apollo 11 project and served as president of RPI, and astronauts John L. Swigert, Jr., Richard Mastracchio, Gregory R. Wiseman, and space tourist Dennis Tito are alumni.
Told you it was boring!
You forgot Mark Watney! Definitely in consideration for most famous alumni for University of Chicago, especially after we got him home safely from Mars.
University of Virginia: Clarice Starling (Silence of the Lambs) and Katherine Trammell (Basic Instinct). Probably John-Boy Walton, as well.
No way!
I think what Colibri is referring to (in a tongue-in-cheek fashion) is the fact that the OP’s intent with the thread was purely for fictional alumni, though a number of posters either didn’t understand that, or didn’t care, and shared actual alumni from their schools. 
Right. So per the title and OP of the thread, she doesn’t belong in this thread. Admittedly, she seems like she should be fictional.
She’s in two episodes of Absolutely Fabulous, so maybe a fictional version of Twiggy does exist and went to that school.
She’s just a character from The Blues Brothers. She’s obviously not a real person; that would be absurd.
My bad, I didn’t realise it was fictional only.
There are these crazy things the kids these days are all calling “thread titles”… 
Honestly the title could be parsed two ways:
Most famous or interesting alumni or fictional alumni (in which famous/interesting is one category and fictional is another. Either of those categories would be fun to discuss);
Most famous or interesting fictional alumni (in which famous and interesting modified fictional). This sees to be what the OP intended, but it can be read the other way.
Given that all of the examples given by the OP are the latter, it’s pretty obvious that’s what he meant.
Yes, which is why I said that’ it was clear that’s what the OP meant.
It wasn’t obvious, I guess, that I was replying to the post above mine that critiqued people not reading the title.
It was the title I was addressing
In my opinion, the title is pretty clear. You have to both parse the title wrongly, and not read the OP to misunderstand the point of the thread.
Yes, it was clear to me as well. However, it is not unreasonable that some people, who did read the title (like the poster was suggesting they didn’t do) can parse it differently.
Having written 100s of crystal clear (to me) assignment or exam instructions, it’s obvious that well intended people just read things differently.
Again, taking the OP text out of the argument- I was replying to the idea that just reading the title was the only act needed to get it right. I found the two potential parsing an interesting observation.
Clearly, YMMV
Just shows to go that you should read both the title and the OP before posting. If I had a nickel for every time someone gave an example that was already listed in the OP (often exclaiming "I can’t believe no one else has posted this yet!), boy, would I have a lot of nickels.
But not perfectly /clearly/ (But it’s OK: I didn’t have anybody /famous/ either.)
I don’t have anybody, unless I can count Ronny Chieng semi-autobiographical:

– which I do, because it’s a whole fictional netflix short series set at my university.
I think Major John D. MacGillis from Major Dad went to Vanderbilt. I can neither think of nor google anyone else who did.
