Because there are so few GOP presidential candidates remaining, last week the final four were given Secret Service protection, and the opportunity to choose code names -- which were made public.

In this preview of Friday's new "Real Time," Bill Maher asks, doesn't that sort of defeat the purpose of a code name?

Watch Maher make fun of Rick Santorum's chosen code name above. "Real Time" airs Fridays at 10:00 p.m. EST on HBO.
