this little bit first showed up on salvidor dali's birthday episode. craig ferguson was talking about dali and the randomness of the dada movement, this being an example of that randomness. when craig puts his hand to his head and goes 'oooh!' then this picture of dali slides onto the screen and goes 'oooh!' craig has since ooohed many times, and usually at the most unusual moments too! a follow up to this bit is the double oooh!, which shows a picture of a giraffe when ever craig puts two hands up to his head and goes 'oooh!'. there is no sense behind it, its just funny!
