Ok so strictly speaking it was a specific mustard colored rectangular Tupperware bowl that often held soup leftovers in the fridge. Occasionally it held popcorn. For a small child who was sick and couldn’t reliably get over a toilet to puke, it was the designated “puke bowl.” For the record, I don’t believe poop knives actually exist, but in this instance, your wife is correct.
Always liked Power Pete, and if you don’t have vertigo, the Descent series.
