I've done my share of drinking but not since the Internet was in place, so no. But I've posted lots of stuff that I don't remember doing, and I've had lots of stuff published that I don't remember writing, but there it was with my name on top. Lousy memory.
I'm not alone.
Isaac Asimov looked up an obscure subject in Britannica and was so impressed by the way it was written that he looked up the author. Yup, he'd written it himself.
