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.
Another one bites the dust. RIP Harold Ramis.
The Sharp Single 
A very funny film, a very funny man …
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.
We could go on like this all weekend …
