I just wish Ben and Kate wasn't a tired old improv class project with Nat Faxon using his patented "idiot expression" based on pretty much every other character he played.
You're not married! You're brother and sister!
Riffing on an inappropriate and/or random subject endlessly with short awkward pauses!
Unison improv of a song by looking at each other!
Deliberate and forced nerdiness deploying the use of buck teeth!
Slutty girl speaks inappropriately to a child!
"Awww" moment at the end!
It's just a Mad Libs series.
