Coworker in my team recently said to boss:

"Thanks, this conversation with you has taught me so much about single-threaded blocking I/O"

Some random PR comments from our company's repository:

"Are you insured? I hope you are insured"

"Learning git is not that difficult. You only need one command: git reset --hard"

*Link to amazon for dog poop bags*
"Please clean up your shit, before I step in it"

"Have you thought about a career in sales? At least there you might sell your bullshit"
