It’s Halloween – or almost, depending on when you’re reading this – in the US, and it’s a big deal here. I read somewhere that it has become a bigger holiday than Christmas for retailers – can that be true?

I got to thinking about the scariest moments public speakers have, naturally enough, and compiled this top 10 list for your perusal. This list is compiled from my own personal disasters and those of my clients. Let me know what your scary speaking moment is, and I’ll give a prize to the scariest one, decided by me, arbitrarily based on the hackles risen on the back of my neck.

10. You realize that you forgot a key piece of your argument 10 minutes back.   You’re in the middle of your speech and suddenly you realize that you forgot a vital piece of the argument minutes ago. It’s too late to go back, yet the audience is going to be confused by your next leap of logic. You’re going to have to interject the forgotten bit, but it’s going to make you look disorganized. Scary!

9. Someone asks a question you can’t understand. I was talking to a multi-cultural audience once, and a very nice man asked a question that was both esoteric and in heavily accented English. I just couldn’t get it. I asked him to repeat the question twice, but after that, I had to make a guess, because it would have been awkward to keep asking. Painful!

8. The questioner won’t stop. Of course there are people who ask questions just to hear themselves talk. So, liking the sound, they keep going. You don’t want to be rude, but they’re hijacking the show. I ran into this recently where the questioner wanted my opinion on the storyline of a movie – so he told me the entire storyline. I aged 5 years during his recitation. Creepy!

7. The technology freezes. We’ve all been there on this one. The slideware suddenly freezes, and you’re revealed for the duffer that you are in trying to figure out why it has frozen. The secret solution for this one is to ask for help from the audience – especially if it’s an audience of engineers – because they’ll be nice and help you, and then it’s not your problem alone. But will you remember to do that under pressure? Terrifying!

6. No one shows up. What do you do when there’s no audience? I once took part in a fundraiser where we speakers were supposed to bring a half-dozen potential donors each. All of us assumed everyone else would do it, and so we didn’t. The result? About six people in a space designed for 150. Mortifying!

5. Your tech is incompatible with their tech. I learned this one the hard way, showing up once with technology that wouldn’t work with the super-sophisticated system the IT folks had in place. Now, I carry backups, alternatives, dongles, thumb drives, you name it. I’m ready for anything. Aaaaaargh!

4. A heckler starts in on you in the first few moments of your talk. This happened to me years ago, when I was still an academic, and someone from another philosophical camp attacked the premise of my talk. I was new to the game, and instantly derailed, spending the rest of the time on the defensive. I’ve since learned how to defuse hecklers, but it is a nightmare scenario nonetheless. Help me!

3. The lights go out. This one happened recently to a friend of mine. The talk was proceeding well, and then suddenly it all went dark. It’s frustrating, baffling, and alarming all at once. What do you do? Keep talking? Vamp, hoping the lights will go on in 60 seconds? Give up? The show must go on, but how? Nooooooooo!

2. The conference organizer changes the game on you at the last minute. This one happens more often than you’d believe. The organizer comes to you, saying, “We’re running 40 minutes behind because the CEO ran long. We need you to get your speech done in 20 minutes instead of 60. The lunch can’t wait.” Really?

1. The next speaker doesn’t show – so you’re on. The keynote speaker is delayed due to weather and you – for a host of reasons – are it. This happened to me once in Vegas. There was a minimal team from our company, the host, and I was the only one with the credentials to speak.   I was told, “Keep ‘em amused for 90 minutes. There’s a chance the real speaker will have landed by then.” Nightmare!

What’s your scariest speaking moment, besides the first one of every speech?
