Emus can be quite a big problem in the "land down under." Take a look at the above photo, for example. The police had to intervene because two emus, a male, and a female, had blocked several streets in the city, becoming a hazard for everyone involved. Luckily, police in Australia are nice (they are almost Canadian in nature), and they didn't harm the two large birds - how could they, just look how cute they are.
Eventually, the emus were taken to safety and hopefully they learned their lesson to not block streets again. Although other emus (and probably kangaroos, since this is Australia we're talking about) probably do block the streets in Australia on a frequent basis. That shouldn't even be such a bad thing, as just seeing exotic animals on the street can be enough to make anyone's day better.
