Q: Why did they throw the babcia (granny) off the tram? A: Because she wouldn't give up her seat to a tired student.
Tram passing by (Christopher Anderson)
I read this joke on a Polish listserv. It's funny if you've ever been on a tram or bus in Poland and had the temerity to not immediately relinquish your seat for a babcia. It's not like here, they'll let you know the right thing to do--for that matter, whether your child is dressed appropriately for the weather.
