Wherein the photo bombing begins

The busy morning yesterday with Bubby and Mac — most of which involved playing at the community pool — soon overtook Mac. He couldn't help but give in to the exhaustion... and Gramma couldn't help but photograph the pooped-out kiddo.

And Bubby? He obviously couldn't help but photo bomb his brother.

Today's question:

Who most often plays the photo bomber in your circle of friends and family?
