Gee, it’s geology! in this week’s Dadding Badly. http://www.gocomics.com/dadding-badly/2016/11/28
One place we went was the MAD Magazine offices, where Art Director Sam Viviano gave my kid this mask. This was also the time that my kid got the entire editorial staff* to sit on the floor to play a rousing game of “roll the ball.”
* there were only three in the office that day.
