'Howard Stern Show' sidekick Artie Lange has missed more than a week of work and fans want to know what's up. Lange's mysterious absence shot the 42-year-old comedian's name to the top of Google Trends this morning. His audience is wondering - is he just sick, having caught a cold on a flight earlier this week, as he said on a voicemail left for producer Gary "Baba Booey" Dell'Abate? Or is Lange back on smack, as many, including Howard have publicly wondered.
