Go to hell, you old bastard. — C.J. Ramone, “Rosebud”
First off: take a good, hard look at the Burns shot for twenty seconds or so. Truly unsettling—good job, animators.
The iconic Marilyn Monroe-subway grate scene comes from The Seven Year Itch, a 1955 comedy about infidelity and the human imagination. Monroe plays the foul temptress; she has some pretty good quotes.
The filming of the famous subway grate scene evidently required a bit of work for the director, as the assembled crowd of slack-jawed gawkers refused to stay silent during the constant Monroe upskirt show.
Finally, it’s also worth noting that the real-life “seven year itch” is apparently a colloquialism for scabies. Not so elegant.
