Well, one man has proved that you can squeeze in at least 500 into an Audi.
A man from Kazakhstan was stopped by border police as he tried to re-enter his country following a trip to neighbouring Uzbekistan.
However, he failed to make it through border control when officers noticed that he had live animals onboard.
Upon closer inspection, it became clear that the unnamed man was trying to bring highly valuable parrots into the country.
"Border guards discovered a live cargo of 500 parrots in his car," a KNB security official told Kazakhstan Today.
It remains unclear exactly how the man managed to fit so many parrots in his car but he now faces charges. He might have got away with it if he was dressed as a pirate!
Don't try this at your local border - Trade in wild parrots is banned around the world.
