A Polish sentence which is hard to speak in Poland (about a "worm")

I met a girl in Poland and we had very much fun trying to learn me Polish. Its an interesting language and i wanted to show her that i tried.

She told me there is a very hard sentence in Poland to speak, it goes about a "worm" named "shauntzt" (this is not the correct spelling, but its as close as i can let it sound what she said)

Does anyone has this sentence for me?

I think it's about a beetle:
"W Szczebrzeszynie chrząszcz brzmi w trzcinie"

Enjoy trying to pronounce that ;)

Thank you very much Looker. I will try my very best.

you can use ivona. to hear the correct Polish pronunciation Sebas - the interface is pretty intuitive - you will figure it out

A longer version is:
Chrząszcz brzmi w trzcinie w Szczebrzeszynie, a Szczebrzeszyn z tego słynie.

A beetle sounds in the reed in Szczebrzeszyn (name of a town) and Szczebrzeszyn is famous of it.
