Somewhat funny: ancient cudgel's push ability

I was doing the story mission "Temple of the Forgotten God" and on a lark I picked up one of the Ancient Cudgels lying on the ground. It has one attack, Whirling Strike, that has push. If you use it and chase your target, you can push the target through the walls and pin them. If you turn on auto-attack it's pretty easy. I did this several times in the first part, pinning the first two Devoted, and a couple of various Risen. Some of them managed to get back out after a couple of minutes, but they couldn't always do it.

I have a couple of screenshots showing this but I don't know how (or if you can) post them here.
