<human>: Last night, after dinner at home, my wife outlined a number of things she needed me to do as she was quite busy with some deadlines at work. We live in a fairly dynamic house where we both share the chores and responsibilities very equally, and this has never been an issue. However, my coping mechanism is humour, and after a pretty hard day at work, I jokingly said "OK, führer".

Normally, she'd take this with a grain of salt, however I failed to notice our 4 year old son standing right behind me in the kitchen. As I chuckled after saying this, he thought it was funny, and then said, "OK führer", a number of times, and laughed quite hard after saying it.

The glare I got from my wife at that point is indescribable. I think that men have turned to pure concrete after meeting this glare.

Our 4 year old then proceeded to walk up to our 18 month old in his high chair and repeat it a few more times, laughing again each time.

I had to sit him down and tell him that what Daddy said wasn't actually very funny and it was inappropriate and that he DEFINITELY should not repeat it at kindergarten tomorrow.

So, now I'm at work worrying and wondering if he is going to repeat those words. He is a fairly mature boy for his age so I guess  he's learnt that he shouldn't and can distinguish right from wrong in a lot of cases, so maybe I shouldn't worry. Big mistake, though.

Can you condense the text into three sentences or less?
<bot>: I referred to my wife as führer and with my son present and now I'm worried that he'll use that word a lot.
