When comedy legend Harold Ramis died early Monday morning at his Chicago-area home, he was surrounded by family and friends. But those who could not be close to him took to their respective social media platforms to mourn both the actor/director/writer and one of his most beloved characters -- Egon Spengler of the 1984 classic “Ghostbusters.”

Ramis was also responsible for films like co-writing the blockbuster comedy "National Lampoon's Animal House" and directing such films as "National Lampoon's Vacation," "Analyze This" and "Analyze That." Most recently he directed a few episodes of "The Office."

"His creativity, compassion, intelligence, humor and spirit will be missed by all who knew and loved him," his agent said in a written statement, according to CBS News.

On Monday, “Ghostbusters,” “Animal House” and “Caddyshack” all were trending topics on Twitter, along with his character Egon Spengler.

“RIP Dr. Egon Spengler,” @Im_TheLibrarian wrote. “May you continue collecting molds, spores and funguses in the afterlife...while haunting your fellow Ghostbusters.”

“Oh man, Ghostbusters has forever been one of my all-time favorite movies,” @10thousandroses tweet. “So sad to hear about Harold Ramis. RIP Egon Spengler. <3”

“So sad about Harold Ramis, Egon Spengler aside Caddyshack, Groundhog Day and National Lampoons Vacation are all classics of their time,” @richardnorris75 added.

Some of Egon’s most memorable quotes from “Ghostbusters” have been posted below, courtesy of the Internet Movie Database:

Dr. Egon Spengler: Oh good, you're here!

Dr. Peter Venkman: Yeah, what have you got?

Dr. Egon Spengler: This is big, Peter, this is very big. There is definitely something here.

Dr. Peter Venkman: Egon, this reminds me of the time you tried to drill a hole through your head. Remember that?

Dr. Egon Spengler: That would have worked if you hadn't stopped me.

Janine Melnitz: You're very handy, I can tell. I bet you like to read a lot, too.

Dr. Egon Spengler: Print is dead.

Janine Melnitz: Oh, that's very fascinating to me. I read a lot myself. Some people think I'm too intellectual but I think it's a fabulous way to spend your spare time. I also play raquetball. Do you have any hobbies?

Dr. Egon Spengler: I collect spores, molds, and fungus.

Dr. Egon Spengler: There's something very important I forgot to tell you.

Dr. Peter Venkman: What?

Dr. Egon Spengler: Don't cross the streams.

Dr. Peter Venkman: Why?

Dr. Egon Spengler: It would be bad.

Dr. Peter Venkman: I'm fuzzy on the whole good/bad thing. What do you mean, "bad"?

Dr. Egon Spengler: Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light.

Dr. Egon Spengler: I think this building should be condemned. There's serious metal fatigue in all the load-bearing members, the wiring is substandard, it's completely inadequate for our power needs, and the neighborhood is like a demilitarized zone.

Dr. Egon Spengler: Sorry, Venkman, I'm terrified beyond the capacity for rational thought.

Dr. Egon Spengler: I feel like the floor of a taxi cab.

Dr. Egon Spengler: Venkman, shorten your stream! I don't want my face burned off!

Dr. Egon Spengler: Not necessarily. There's definitely a *very slim* chance we'll survive.

Dr. Egon Spengler: Let's say this twinkie represents all of the psycho kenetic energy in the New York area. According to this morning's sample it will be a twinkie, 35 feet long and weighing approximately 600 pounds.
