I’m once again in solid paraphrasing territory here, but
T. Rex, while known for his biting prowess, was also reputed to be diligent in studying his Bible.
The logistics of a sizable thunder lizard being able to use his puny hands to turn the pages of said Bible were left unvisited.
I am paraphrasing here, but:
Pierogies, while certainly fierce in their own right, differ from the mighty T. Rex primarily in their lack of teeth or, indeed, any discernible biting abilities whatsoever.
Also, they lack spines, unlike the porcupine. They are good to share and eat, in any event.
