Dick using the phrase in 'Dicks First Birthday'
'Oh My God, I'm Gorgeous!' is a catchphrase used by Dick Solomon. The phrase was first used in the episode Dick's First Birthday, when he dyes his hair black for fear of getting old.
It usually involves Dick looking at himself in a mirror and reflects his narcissistic character. The phrase has also seen some variations, such as 'Oh My God, I'm Hideous!'
Sally has also been seen to say this phrase in the Season 4 episode Two-Faced Dick, although Dick and Sally have swapped bodies.
