What is something that scared the ever-living shit out of you but looking back seems hilarious?

I’m still working on it but I’m trying to remove scary things from my life that aren’t actually scary. Like clowns for example, they literally don’t scare me anymore. And I’ve kinda started to view things that scared me when I was a kid as funny. Like the exorcist, that movie scared the shit out of me but now it just seems fucking ridiculous.
