Where do they make Christmas toys? - In a manufactory. (With "Manu" being close to "Manó", which is "Elf" in Hungarian. So basically, the "Elfactory" 🙂 ).
"How do chickens go on strike? - They boycott the eggs." (Note: "Boy" sounds similar to "Toj (Toy)" in Hungarian, which means to lay eggs. So the joke is, they "Toycott the eggs")
"What happens when a robot gets hungry? - It's stomach will rumble." (rumble is also used in Hungarian for the creaky, squeaky sounds of old or faulty machinery)
