The Moozie beards are kinda becoming an annoyance, yeah. As are the tattoos, "natural" balsa-wood physiques, MMA heroics, etc.
It's simple. The funny kid approached Pubebeard, basically casting a shadow over the guy, and Pubebeard just stood there. No, it would not have been wise to physically attack him, from a career perspective, but he did make the ol' come-say-that-to-my-face threat, after all.
Kid's clowning Pubebeard with biceps shots and wagging tongue and ... nothing.
Time to move on.
