I have a friend who was convinced someone was stealing their pencil lead (I was). So I put things like "pencil, mechanic pencil, pencil lead..." at the bottom of emails in white text so that google/bots would target their ads to be about mechanical pencil lead. He freaked out thinking it was some conspiracy to get him to buy lead Source
You know those 6 button combination door locks? I used to press one every time I walked by my boss' office. Every time he tried to get in it would take 2 attempts. Every time I tried to get in it took one, because I knew there was a button pressed. He has me change the lock, twice, and never figured out what was going on Source
I have a pretty good memory when it comes to stories that my friends have told me, so I like to retell their own story to them a year or two later (now starring myself) and see how long it takes for them to catch on. They start off with a look of "oh man, I can tell a similar story as soon as he ends his!" Then it turns into a look of "Wait, that's my f------- story!" Source
In the first few weeks of starting a new job, I kept pointing at the basket of bananas in the break room and asking, "Hey, I keep seeing people take these. What are they for?" and then having a coworker explain bananas to me. I'd usually walk away after saying, "Oh, I had only read about them in books" Source
I like to bring snacks to work on April Fool's Day. Usually, I'll pick something cream filled like donuts or cupcakes. I've done this for over ten years at my current job. It makes everyone suspicious and straight up messes with their minds trying to figure out what I've done to the snacks Source
A buddy of mine will randomly wish me happy birthday on Facebook when it's not my birthday so then a bunch of other people will wish me a happy birthday and I have to explain its not my birthday. This f'er does it every year. A couple of weeks ago he posted on my wall "congratulations man I knew you'd land that opportunity, so proud of you". That followed by a couple dozen people asking me what i had accomplished Source
Get them heavily involved in a good conversation, while standing, and just hand them something. Don't look at it, keep the conversation going, keep eye contact, and hand them anything from a tennis ball to a rock you just picked up. Almost every time they'll grab it without thinking. Works even better if talking and walking. See how much stuff they can hold Source
The opposite also works. If you get someone very involved in conversation, and they are holding something like their phone, and you reach as if to take it, they'll often just hand it over without thinking. I did that this morning to the guy I was relieving at work, as he was telling me about his night, and he handed me half his personal equipment. It wasn't until I started attaching it to my own belt that he was like "wait, what, what are you doing, give that back!" Source
I used to work in a call centre a few years ago. We had to take customers details and I'd always repeat them back to make sure they were correct. Whilst doing this though I'd f--- with them by saying things like "oh is that k for knife?", "P for pterodactyl yeah?". Good ol' silent letters Source
When I'm on a waiting list at a restaurant, I always put the name down as Parpar.
About half the people kind of hesitate or look at you weird. Play it straight and just spell it out if that happens.
When you're called over the loudspeaker, it sounds like they're stuttering. Par-par-party of 4.
You can also do weird/funny names that are just barely believable Source
I have a lazy eye and can make it look forward or at my nose at will without my glasses. So naturally i love to meet new people and after a small amount of time clean the glasses while having a conversation. All the while moving my eye back and forth, watching them try their damnedest not to say anything Source
