A *big* Easter weekend surprise for a family in eastern Europe!

Take a look at this big baby in Slovakia named "Matuako."

Mom delivered him at a whopping 13-point-six pounds!

That's 62-hundred grams if you prefer the metric system.

He's twice the size of the average baby born in the Slovak Republic.

The proud papa says he knows why -- Dad says his family comes from the Tatras Mountains, where men are known for their size and strength!
