My favorite is "Its not my job to do your research for you".. to which i respond "No but id at least have expected you to do yours".
@freemo Haha that's awesome!
@freemo feels like you didn't research this topic enough
@AncientGood Really? Cite your source!
@freemo I love responding to these people by saying "so you don't know" or "so you just made that up then"
