Newbies rule number 5. When preparing a turkey always take the bag of giblets out of the cavity before stuffing goes in...
No Kidding! Ah, when my mom died unexpectedly when I was a teen and I took over the cooking in the house (Dad worked all day) though her friends taught me a crash course in bachelor cooking, I still made a similar omission with a stewing hen. Pressure cooked the darn thing with the giblet bag still in it. When it came time to dissect the beast to go with the noodles, that's when I discovered the plastic oopsie inside. I guess that's less embarrassing than having your guests discover it!
