Ted Kennedy: He may have died in 2009 and we're almost at 2013, but still this dude is as relevant as ever. I'm glad Howard hasn't quit doing impressions of him.
Tiki Barber: He last played in the NFL during Howard's 1st year at Sirius in 2006, and NBC may have dumped his ass in 2010, and he was not on the NY Giants' 2 Super Bowl-winning teams. But this dude is as relevant as ever. I'm glad Howard is having him on.
Nick Cannon: America's Got Talent ended the season 3 months ago, and the next season won't kick off for another 5 months, but this dude is relevant than ever. I'm glad Howard is having him on.
