So, the title says it all. This thread is about posting one-liner jokes. Short, simple, and funny jokes made of one or two sentences.
Copy and paste away; you don't need to be completely original. If you see a funny joke on a website, feel free to post that.
I'll start off with one that I didn't come up with:
"I've just been on a once-in-a-lifetime holiday. I'll tell you what, never again."
