I've had the surreal moment of attending a workshop where the main presenter (famous) is talking about their soon to-be-published work where I realize that I'm one of their reviewers (months after I wrote the review, so no impact on my score). In this case, I loved their paper and gave it high marks, and so did the other reviewers. Not surprising when I found out who the author was!!!

I have to not say a word to them as I talk to them or else I could ruin the whole peer review thing!

"Hey honey, I reviewed X work from Y famous person today"
