I thought of something.

When I was younger, my family had sheep and every year my mom would bring a few of the babies up for my show & tell. Our whole class was outside on the playground and I had a set of twin lambs. Before we went out, I told everyone not to run up to them because they were easily spooked, but everyone would get to pet them. Well, as soon as they saw the babies, everyone ran up to them and the sheep ran!

They got off of the playground and into the streets, and they just kept running. Someone downtown saw them and called the police. The police went and caught them and I had to go to the police station to pick up my lambs.
