Got Parkinson's?

Ok, there's nothing funny about having Parkinson's, so I’m sorry in advance if this is offensive.

I saw a bus just like this one in the mall parking lot the other day, and after recognizing what looks like the Canadian Leaf thingy (I’m not Canadian, for the record), I immediately thought to myself (and started laughing hysterically): “I bet it was a shaky ride from Canada!!”

I'm probably going to hell now. BRB!
