Two cute old ladies, Millie and Fran (like they could be named anything else), are put in front of a green screen pretending they're on a rollercoaster. That's it. Maybe they could be a replacement for Leno at 10 PM?
You take an old person and put them in a situation that is usually reserved for young people, and it's adorable. Granny playing a wii, meemaw hitting a bong, or a granddad rollerblading. Inversely true for babies. Stick a tweed jacket and a pipe in a baby's mouth, immediate awws.
