There I was at work, minding my own business, doing some paperwork, etc.

Smelled a faint hint of gas. Uh oh, that's not good. I followed it down to the basement where it got stronger. Went into one of the large walk-in coolers and the smell was quite strong.

I pulled open one of the drawers and there was Chris McKinstry's body!

Forgot I was in the morgue.

Earlier jokes were too soon.  This one is not too soon.  Soon it will be 'just right'.
