“It was quite by accident I discovered this incredible invasion of Earth by lifeforms from another planet. As yet, I haven’t done anything about it; I can’t think of anything to do. I wrote to the Government, and they sent back a pamphlet on the repair and maintenance of frame houses.”
As a non-native English speaker I just took that line to be a hilarious version of form letter response. "Your business is important to us" replies have been around forever.
If you want to stretch it a bit there could be a pun involving frame-up but I doubt it.
