I had this gif open in a tab once in college. I just thought it was funny and I had it in a portable web browser on my portable hard drive, so I could resume my session on any computer.

Anyway, I opened it one time and a friend of mine went, “Oh shit please get rid of that.”

I didn’t really get it, then they said, “No you don’t understand, I have an irrational fear of Beaker. I had a horrible dream where he was doing surgical experiments on me and he really upsets me.”

I had just inadvertently found possibly the worst version of their worst nightmare and jump scared them with it.
