<human>: This happened a few years ago.  I was reminded of it recently.

For about a month, and for no good reason, I got it stuck in my head to respond to certain questions with "dead in a gutter."  Where's Jason?  Dead in a gutter.  Have you seen my pen?  It's dead in a gutter.  Sort of a stupid twist on "your mom" or "that's what she said."  Much like [sideshow Bob and the rakes] I found it at first amusing, then not really, but eventually again I thought it hilarious.

Really not my finest hour of wit; I honestly don't know why I did it.

Well, at some point it became a bit of habit.  And then one day after about a month of this, my dad and I were out at a relative's house, when I hear him ask in a loud voice "Where is my son?"

"Dead in a gutter!" I loudly shout across the house, thinking nothing of it.  I started walking toward him, then stopped in the middle of my second step.  My eyes widened with horror at what I had done.

The real fuckup?  We were at the funeral reception for my relative's (adult) daughter, the house full of mourning people.  Luckily I had been in a mostly empty room, and either no one in the house really heard me or no one actually understood what it was I said.  There were no odd stares, gasps, or any response of any kind from anyone else there.

I was very quiet for the rest of that reception and I have never again responded with dead in a gutter.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Told my dad his child was dead in a gutter in the middle of a funeral reception held by grieving parents.
