Kind of like Purim torah, but not. :-)
A talmudic take on Thanksgiving by
magid. Excerpt:
What turkey fulfills the obligation? A turkey cooked whole, the bones unbroken. However, if he has only turkey cut in parts, he has fulfilled the obligation. Ground turkey does not fulfill the obligation. Abba Arika says, since it is not distinguishable from other ground meats. Mar Ukva says, because he cannot point at the turkey. A chicken does not fulfill the obligation, but may be served to minors if there is insufficient turkey for all.
