With so many Republican presidential debates, it's getting more and more difficult to find a different angle with which to cover them. So Jon Stewart decided to explore the phenomenon knows as "Mittface" in the CBS debate on 'The Daily Show' (Weeknights, 11PM ET on Comedy Central).

It's the fun of analyzing Mitt Romney's expressions and reactions to what his opponents are saying at any given time. While his expressions are all disturbingly similar, it's fun to look for the nuances that could give us a peek into the candidate most consistent in the polls (he's usually second behind the constantly changing merry-go-round of front-runners).

Can you spot the expression where he's waiting for the GOP to finally concede and admit he's going to be their guy for the 2012 run to the White House?
