In episode four, "Manrattan", a man calles Gary "Mickey". Kelsey Grammer (Gary) starred in the Mickey Mouse cartoon Runaway Brain (1995) as Doctor Frankinollie (an inside joke to the original Disney animators Frank Thomas and Ollie Johnson) and starred as the narrator in Mickey's Once Upon a Christmas (1999).
Gary 'The Rat' Andrews:
Ashes to ashes puts to puts.
There is a slight dialogue change after the first eight eps and the show was moved to an earlier time, Originally, Gary first sees himself as a rat in his mirror and screams in horror, then mutters under his breath, "Gary the Rat. Shit." This line is changed when the word 'shit' is replaced by a rather hurriedly said "This just sucks". This dialogue may have been taken from the episode where Gary is trying to find a date for a business party.
