Has anyone else's rear wiper arm severed its own hose before?

[Vortec6000]

I bought a Dorman replacement rear wiper arm about a year ago and it severed it's own hose a few months ago. I didn't want to put a Dorman one on but I didn't really have a choice. It has split cleanly in half. Purely out of curiosity, am I the only one this has happened to?
