Basically how this works if you find a funny typo or a weird line that you don't understand how that happened or is just funnily bad in your writing, post it here! For example, I'm typing up my handwritten first draft of my novel and just found the line "The ninja laugh loudly at him, and I join in, laughing loudly." Time for me to visit the Department of Redundancy Department...
There's a thread like this on the NaNoWriMo forums called "Nanoisms" that's hilarious and I thought I'd make one here! Hopefully there isn't already a topic like this, if there is tell me and I'll take this one down I didn't see one but I didn't look very thoroughly so I may have missed it!
Anyway I know writing tends to cause a lot of funny mistakes, so here's a place to share them and laugh at those others have posted
