Meeting The Morning Teams

You wake up with these people - in a manner of speaking, and now they're ready to meet you in the flesh. Katie and Matt, Brian and Keisha - first on your TV - Ahhhhhhhhh I have the song in my head again! News Channel 8 have done it, and NBC 30 are doing it regularly - giving you a chance to meet the morning team, even giving the few and the brave and the rediculous a chance to sing that catchy tune and appear in their promos. I haven't had the chance to go meet them myself, but I'm curious about one mysterious member of the team.

Who is NBC 30's Mark The Shark? Why does he have no last name? Is he like Madonna? A quick google search of the phrase reveals a count of 4,790 matches. What is his real name? What kind of shark is he? Hammerhead? Great White? And what happens if a Traffic Reporter gets stuck in traffic?
