Funny Friday....Just Sayin'

On the left is Carl Sagan, as Rob says he is a blast from the past.  

Marnie, I am glad you do not know the girl on the right is Snookie and not knowing the Kardashians is a great thing!  

Jennifer, we are not old-timers but experienced and knowledgeable older teenagers!

Bill, unfortunately sad but true.
