A toddler beating on a drum
In many episodes of BBLiveShow and some episodes of NSFW, Brian has compared himself to a toddler beating on a drum. The similarity is reference to putting on a little Internet show, making some noise, and posting to Twitter the equivalent of "Look at me! Look at me!"...much like a toddler beating on a drum will put on a "show", make some noise, and shout "Look at me! Look at me!" to everyone in the room.
