i personally love both of these incidents. the avery incident shows he doesnt take s*** from other teams. and apparently seabrook and him were really good friends when wizzy was in chicago. so it shows that wisniewski is all business on the ice, will defend his team (even if the other guy is a close friend), and sees himself as a lil bit of an enforcer.
and if you watch that second video a couple of times seabrook acts like his brain stem was just removed. the announcers noticed it, too.
