- Ox, Ox, Ox!

- Yak, Yak, Yak?

This is double meaning Polish conversation.

Ox is Wół in Polish. If you repeat this 3 times It's sounds as www.

Jak is Yak of course, but it is also question "How?"

This is comercial of a daily offer for prepaid mobile internet. You can spend whole day on "Wół,Wół,Wół'

How, how How? Just using Heyah's phone.
