A funny story (I thought so anyway) from Neal at Literal-Minded.
As far as I was concerned, Chad’s use of "myself" was not only a mistake, but a mistake that needed to be corrected, by me, then and there.
“With me,” I interrupted.
“What?” Chad asked.
“Michelle will be riding with me.”
“No-o-o,” Chad said, looking puzzled as he reviewed the drivers and riders in his head. “Michelle will be riding with me.”
“He’s correcting your grammar,” Michelle told him. “You said ‘with myself.’” But even the clarification from Michelle—who had dated Chad the previous year, by the way—couldn’t completely erase the pathetic impression of a jealous loser, stepping up to challenge Chad for the privilege of driving Michelle to the dance. I still cringe when I think about it. Luckily, I have much more embarrassing memories to draw on to make this one not so bad.
Preceded, of course, by a thorough linguistic explanation of reflexive pronouns.
