When I downloaded a virus that turned out to be a troll. It spawned some windows with 'Trololololo...' flashed blue and red and jumped random on the screen while playing troll music.
Closing one window would lead to that window beeing duplicated.

When I got into coding, one of my first projects was a recreation of this.

Confessions of a Programmer

#1
If a client is an unbearable asshole during the initial communication, I look for every excuse to pad on the hours for the estimate to get paid more. If a client goes above and beyond in their douchbaggery, I tack on an additional $40/hour.

#2
Sometimes I will present an elaborate solution to a client, but really I'm just reading off the features of a plugin or library I'm going to download or buy after the call. Not because I can't build it myself, but because I'd rather spend more time on other/my own projects.

#3
Clients assume because I know one language, I know them all. Rather than turning down the work, I take a crash course to work in that language, or outsource the work and clean it up afterwards, whichever is more practical at the time.

#4
I use cPanel on a dedicated to manage our client websites. I'm not paid enough to bother with setting up everything manually.

#5
Certain projects I build have a 3-day backdoor built into it. If the client doesn't pay upon completion, a unique hash triggered as a GET variable deletes a core file in my work, rendering the work useless. If it wasn't triggered by the 4th day, the file allowing me to trigger this backdoor is removed. This is only used for clients where the project must be launched on their servers, or if there has been a previous issue collecting payment.

#6
I slip in the initial contract that all preceeding phone calls will be monitored and recorded, and that they acknowledge the recordings are admissable in court. This has saved me from losing money twice now.

#7
I have never used an IDE. (I know, I know, it's really inefficient and dumb, but I'm just more comfortable with Sublime. Plus I often find myself mobile and without my computer, so I have to program from my phone.)

#8
Each day resembles a betting spectacle of which work will be late, which will be rushed out and which will never see the light of day.

#9
I have used "sick" and "family emergency" as an excuse to just sleep in far more than I can count.

#10
When a client from hell crosses over the line in their conduct (such as getting very nasty and personal, or sending threats), I anonymously report them to the BBB and on RipOffReport.

A tcp packet walks in to a bar and says “I want a beer”, barman says “you want a beer?” and tcp packet says “yes, a beer” .

In high society, TCP is more welcome than UDP. At least it knows a proper handshake.

A bunch of TCP packets go into a bar, until it’s overcrowded. The next day, half as many go in.

A bunch of TCP packets walk into a bar. The bartender says, “Hang on just a second, I need to close the window.”

When I try to send SYNs to chicks, I don’t get any ACKs. Just FINs and RSTs.

IP packet with TTL=1 arrives at bar. Bartender: “Sorry, can’t let you leave…and you don’t get any beer either…” 

The worst part about token ring jokes is that if someone starts telling one while you are telling yours, all joking stops.

The great thing about TCP jokes is that you always get them.

The problem with TCP jokes is that people keep retelling them slower until you get them.

I would tell some UDP jokes too but I never know if anyone gets them

The best thing about UDP jokes is that I don’t care if you get them or not.

I had a funny UDP joke to tell, but I lost it somewhere...

The sad thing about IPv6 jokes is that almost no one understands them and no one is using them yet.

I tried to come up with an IPv4 joke, but the good ones were all already exhausted.

A DHCP packet walks into a bar and asks for a beer. Bartender says: “here, but I’ll need that back in an hour!

DHCP jokes only work when there is only one person telling them

The worst part of SSH jokes is that, even when they're not funny, you suck it up and just pretend they were anyway.

The problem with token ring jokes is you need to wait your turn to laugh

I’d make a joke about UDP, but I don’t know if anyone’s actually listening…
