#define true (rand()%1000 != 0)
in some obscure C or C++ header file on their system/project. This makestrue
evaluate to false one in a thousand times, and will make them spend hours trying to figure out why things like infinite loops, aren’t quite infinite.Other languages should also allow you to do things like this, if not messing with constants, messing with standard library functions.

Andy ( @andrewrgross@slrpnk.net ) 27•10 months agoI’ve heard it said that the key to a benign prank is to creates a mixture of momentary alarm and confusion, followed by relief.
A few years ago, I put a sign on my boss’ office door that said that his office was off limits for the week, as the building facilities team was going to be proactively placing humane termite traps in his office for two weeks as a preventative measures to lure any termites in and then release them at a nearby forest. He found it amusing.
Hamartiogonic ( @Hamartiogonic@sopuli.xyz ) 26•10 months agoTrue story. This thing happened last week.
Person A: I want to eat something.
Person B: Do you want some of these (B opens a box of boring cookies and shows the contents to A)
A: No!
B: How about these (opens another box of bland cookies)
A: No!
B: (grabs a third box, realizes it’s empty, but opens it carefully not to show anyone what’s inside) Ooh, I’m not showing this to you. (Puts the box away.)
A: I wanna see! (Tries to grab the box)
B: No, it’s mine! (Pushes A further away)
After some futile struggle B let A have the box. A opens it up and realizes it’s empty. We all had a good laugh.

Radioactrev ( @Radioactrev@reddthat.com ) 21•10 months agoOn the computer thread, changing the keys on their keyboard is also fun. Works better if they are a touch typist as well, as they may go several hours/days before noticing, until they have to look for that one special key. :)

Nyla Smokeyface ( @Nyla_Smokeyface@beehaw.org ) English14•10 months agoI saw a video once of a prank where two girls go up to a stranger asking them to take a picture of them across the street. The stranger takes the photo and when the two girls start crossing over to the other side, a car passes by and the two girls are replaced with two old men wearing the same shirts. Even the Polaroid photo shows the old men. It’s genuinely funny and completely harmless. It just makes the person getting pranked go, “Wait, what the fuck???”
I do hope the people were told that they were pranked though and that they don’t live the rest of their lives thinking they’re insane 😂
ETA: also this video where the guy puts on the collar and leash of his blind husband’s service dog when he asks him to go get his watch. (He immediately reveals himself when the blind husband gets back to pick up his service dog’s leash again and the husband thinks it’s hysterical).

dan1101 ( @dan1101@lemm.ee ) 9•10 months agoIf they leave their phone unattended take funny selfies and then quickly return their phone to exactly where they left it.
oh, I’m going to do this one to my partner
dan1101 ( @dan1101@lemm.ee ) 5•10 months agoI have another in mind but haven’t tried it. If they leave their phone unattended, take a picture of their phone sitting there. Then later on text them the photo and say “You left your phone (wherever)” You will get them to view the photo of their phone on their phone and if you’re lucky they will go looking for it when they already have it.

Cyncit ( @Cyncit@lemmy.ca ) 6•10 months agoI made a “spray grenade” to my friend once. Attached a Ty-wrap to a bottle of Febreeze (trigger in) and throw it in his room while he was there. He was pretty quick to seek scissors and cut it but I can imagine it worse without his quick thinking and a worse scent.

Record satanic rituals on a voice recorder. Tie string around it, open window quietly, lower voice recorder to hover above downstairs neighbor window. Set it to play. Can freak religious people out.
