Carolyn,
The Joey+Friends+Mac n Cheese thing is this:
On "Friends" Joey auditioned for a show (and won the starring role) as Mac, in this show called "Mac and Cheese" Cheese was a robot. The show got cancelled before it even aired.
When I saw the title that's what I thought of first, Joey's show...not the food....cause we call it Kraft Dinner (or KD for short) here. I'm not used to hearing it called Mac n Cheese!

LOL!!!
