I've recently become obsessed with these posts depicting conversations between designers and clients or coworkers requesting "quick" design favors... usually, you know, things like logo design (I mean, really? It should be fast...) or photo retouching... The best one I think I've seen recently was this one about a coworker and her lost cat...

The request calls for a poster to help find this woman's cat. With each edit she asks for, the posters becomes more and more ridiculous. For some reason I can't help but laugh along with the conversation. After all, it shouldn't take more than a few seconds...
“What is this invoice? You said you charge $75 an hour. This animation is only 20 seconds long! That’s 42 cents, and that’s if we’re generous and round it up! This is what we agreed to!”
