Siroti mali hrcki (1973)

The two employees who work in a ministry of card punch set in a basement decide to kill their boredom by coming up with the most stupid quote ever, and then calling random people and telling them the said quote. A harmless joke turns into a public uproar which leads to an anti-terrorist campaign, a police interrogation, loss of the state credit and government change. Them two are unaware of all this, while comic and unbelievable events come one after another.
