Frank,
it is called "Thank god Your Here" basically they get Comedians, TV celeb's, Rock Star's, Radio Personalities etc and get them to walk through a door into a scene they have never seen before, and they have to ablib the scene...the first line spoken to them by the "on the scene players" is ...."OOOOH GOOD THANK GOD YOUR HERE!!!".with the funniest results. The bit you put up is the middle of the show they put the guest "actors" into a situation eg: being a pilot and then through a setup reporter at them and ...well you saw the results
they did a car salesman one once it WAS HALARIOUS!!!
THIS IS ONE OF THE CLASSICS
