It's a glimpse of Common Czech. :) This is the way we speak in Prague and in most of Bohemia. :)
Note the so-called 'prothetic v-' which is added to words beginning with o-, that's very common.
So if I want to sound Czech, I just have to add a v to every word beginning with o? :D
A guy from Prague gets on a train and enters a compartment where there is a guy from Ostrava sitting and says to him: "Posuň se až k voknu." The guy from Ostrava does nothing, only looks around baffled. The Praguer repeats: "Posuň se až k voknu." to which the guy from Ostrava replies: Tak už kvokni, ty ****.
(If you have not understood, it's a joke and the sentence "Posuň se až kvoknu." means "Move yourself after I cluck. [where "cluck" is the sound made by a hen]). :-)
