Ben loves to sing bits of songs he likes, as well as his own ditties (such as "A la la la Bubbe; A la la la Big Bird; Hef! Hef!"), often at the top of his lungs, and anywhere he feels like it when inspiration strikes, from a walk in the woods to a jammed McDonald's line of startled customers. Or, like here, sitting on his bed, June 21, 2015.
