Mobster

There is a tall, built guy wearing a black leather duster jacket, trilby hat, and scowl on his face. He is using his phone, a large smartphone, to likely keep in touch with his soldiers. 

Between his fingers in the hand that is holding the phone, is a ziplock filled with cereal. My guess is that it is snack for later. 

Joey Bag-a-Cereal gets peckish between hits. So where does he go for satisfaction? Boom! Cheerios.

Youse gotta prahb'm wit dat?

Note: there is a Cereal Killer joke in here, but that felt trite.
