Missoula Puns

My Dad, my step-mom, and I visited my step-sister in Montana(we live in Washington) where she goes to school. We had a fun weekend with her all throughout Missoula. My step-mom and step-sister have a a really close bond so when it was time to say goodbye it was tough for them and they both started crying. My dad said something close to "Look now your mother is crying," to which my sister says "Why are you worrying about her I have to walk through people like this." To which my dad hits her with the most dad joke of a dad joke I've ever heard him say. "Why don't you just walk around them instead?"
